I compared 4K Blu-ray to regular Blu-ray, and the difference was smaller than I expected

I recently ran a test comparing an upscaled DVD on my Nvidia Shield to 4K streaming, and the results were intriguing. It was a closer contest than I expected; I knew I couldn't watch streaming without seeing compression artifacts. When it comes to media, we want the best quality possible. But I don't assume something is better just because we're told it is. So, I was curious about the quality and price difference between a UHD 4K and a standard (non-upscaled) Blu-ray disc. Is the difference big enough to justify $10-15 more per disc and gigs of server space? Creating a uniform comparison Same movie, TV, and Blu-ray player setting adjustments I chose a movie from the MCU because it has spectacular visuals, color, and detail. I picked Spider-Man: Far From Home since I've seen it enough times to know what to look for in key scenes. I played both discs on the same Panasonic DP-UB820 UHD Blu-ray player through a Vizio 4K TV. I also kept the same TV settings to avoid skewing my anecdotal test. I restored the TV's settings to default and used the TV's default calibrated dark setting with no other picture adjustments. Another issue I had to address is that my Blu-ray player upscales standard Blu-ray discs to 4K by default, which is a nice feature, but not for this test. So I went into its settings and changed the resolution from 4K to 1080p. I switched the player's output to standard Blu-ray and left the TV to handle scaling to fit the 3840×2160 pixel resolution display. I wanted to ensure I was getting the full visual experience of the 1080p Blu-ray without upscaling getting in the way. I did this test with the actual discs and not Blu-ray rips. I wanted to ensure I was using the full amount of data each disc contains to compare picture and sound quality. Even a properly ripped MakeMKV Blu-ray remux copies the disc's audio and video without re-encoding, but server and network issues can still affect quality. Transcoding, tone-mapping, and network issues can affect playback. Using physical discs, the same player and TV kept the playback devices consistent without introducing media servers. Regular Blu-ray looks great The movie on the disc was impressive After adjusting my player's settings, I watched the full movie starting on the standard Blu-ray at its native resolution. It looked good. For a Marvel flick, the colors popped, scenes were clean and tight, and the movie was enjoyable. It certainly didn't have grainy DVD quality. I wasn't thinking about what I might be missing, and I never felt the urge to pop in the 4K UHD disc while I watched. Overall, nothing about the picture irked me. If I weren't doing this comparison, I would have been satisfied with the regular Blu-ray version without thinking about resolution at all. In fact, if I was watching the movie on the screen, it would have been satisfying because I was absorbed in the story. I wouldn't have known it was lower resolution than 4K. Details were clear in the scenes; nothing looked muddy, noticeably off, or hard to distinguish. I couldn't pick out anything wrong like I can on so-called 4K streaming. Testing the UHD 4K disc From HD to ultra-HD wasn't a huge difference After adjusting my player's settings, I watched the full movie starting on the standard Blu-ray at its native resolution. It looked good. For a Marvel flick, the colors popped, scenes were clean and tight, and the movie was enjoyable. It certainly didn't have grainy DVD quality. I wasn't thinking about what I might be missing, and I never felt the urge to pop in the 4K UHD disc while I watched. Overall, nothing about the picture irked me. If I wasn't doing this comparison, I would have been satisfied with the regular Blu-ray version without thinking about resolution at all. In fact, if I was just walking by the screen to watch the movie, it would have been satisfying since I was absorbed in the story. I wouldn't have known it was lower resolution than 4K. Details were clear in the scenes; nothing looked muddy, noticeably off, or hard to distinguish. I couldn't pick out anything wrong like I can on so-called 4K streaming. The 4K Blu-ray looked better, but a standard Blu-ray is no slouch It wasn't a way better experience in 4K When I popped in the UHD 4K disc after watching the standard Blu-ray version, I was expecting it to look better, and it did. However, it wasn't a magical new experience that made me never want to watch a 1080p disc again. I remember the jump from DVD to Blu-ray, and it was a major contrast in quality. A standard Blu-ray already displays detailed textures, colors, and clear images, which gives UHD something to build on. But the quality difference between standard Blu-ray and UHD isn't there. Not all standard Blu-ray discs look as good as my Spider-Man — the source material, mastering, and compression by studios and production partners matter. Blu-ray.com gave this disc a five-star rating for audio and video. Still, it's worth comparing versions to see whether a standard disc is good enough. I'm glad I did this test and found that, at least for modern movies, it might be enough. Many of my UHD Blu-ray discs include the standard Blu-ray. I'm going to do more comparisons, and potentially start saving much-needed storage space on my media servers. I can rip the Blu-ray and replace the 4K files. I will need to see how standard Blu-ray rips perform, but if they hold up, I can start saving on storage. I won't go as far as only buying standard Blu-ray. But if I can spend less on server storage and keep my library, it's a win. Standard Blu-ray is great, and a cheaper solution in many ways If you don't have a super high-resolution TV set, a standard Blu-ray looks great. Unless you're a videophile, even on a TV with incredible resolution, you won't notice the difference until you watch the versions back-to-back. The bottom line is a modern, properly transferred standard Blu-ray is great, but 4K does look better. But it isn't as impressive as the leap from DVD to Blu-ray. Now, I'm rethinking how I rip and replace files in my media library. Or at least re-encode 4K rips. I'm not going all in on standard Blu-ray. Future-proof media and having choice is nice. But storage is at a premium, and prices aren't going down anytime soon.
