    My roommate always corrects me when I make this same point, so I’ll pass it along. Blu-Rays are compressed using H.264/H.265, just less than streaming services.

        Or worse. I think it was the original Ninja Turtles movie that I had owned on DVD and the quality of it kind of sucked. Years later I got it on blu ray and I swear they just ripped one of the DVD copies to make the blu ray disc.

          Sadly, that basically feels like what happened with The Fellowship of the Ring’s theatrical cut blu ray, too. It just doesn’t look that great.

          Then the extended edition has decent fidelity but some bizarro green-blue color grading.

      People don’t like hearing this, but streaming services tune their codecs to properly calibrated TVs. Very few people have properly calibrated TVs. In particular, people really like to up the brightness and contrast.

      A lot of scenes that look like mud are that way because you really aren’t supposed to be able distinguish between those levels of blackness.

      That said, streaming services should have seen the 1000 comments like the ones here and adjusted already. You don’t need bluray level of bits to make things look better in those dark scenes, you need to tune your encoder to allow it to throw more bits into the void.

        I fail to see where TV calibration comes in here tbh. If I can see blocky artifacts from low bitrate it will show up on any screen unless you turn the brightness down so far that nothing is visible.

        Lmao, I promise streaming services and CDNs employ world-class experts in encoding, both in tuning and development. They have already poured through maximized quality vs cost. Tuning your encoder to allow for more bits in some scenes by definition ups the average bitrate of the file, unless you’re also taking bits away from other scenes. Streaming services have already found a balance of video quality vs storage/bandwith costs that they are willing to accept, which tends to be around 15mbps for 4k. That will unarguably provide a drastically worse experience on a high-enough quality tv than a 40mbps+ bluray. Like, day and night in most scenes and even more in others.

        Calibrating your tv, while a great idea, can only do so much vs low-bitrate encodings and the fake HDR services build in solely to trigger the HDR popup on your tv and trick it into upping the brightness rather than to actuality improve the color accuracy/vibrancy.

        They don’t really care about the quality, they care that subscribers will keep their subscriptions. They go as low quality as possible to cut costs while retaining subs.

        Blu-rays don’t have this same issue because there are no storage or bandwith costs to the provider, and people buying blu-rays are typically more informed, have higher quality equipment, and care more about image quality than your typical streaming subscriber.
