It’s a lot of work figuring out what movies support the format. And all the premium upgrades to Netflix, etc get them to stream premium formats. Then it doesn’t work and you’re spending 30 minutes debugging your TV, wondering why you’re not getting the amazing new restoration of 2001: A Space Odyssey.
I totally understand why people just buy physical media.
Games may be harder given software updates. But I’d pay a premium for a physical copy of mature games I love (like Halo Master Chief collection)
And the 4K video is compressed to lower bitrate than a 1080p Blu-Ray anyway.
My experience is that people don't care about quality. Like there was that time I found a torrent for a movie that had 3000 seeds and found that it was shot with a camcorder in the theater and the soundtrack was in Russian but it didn't matter because the sound quality was so bad I don't think I could have understood the dialog if I knew Russian. Thing is, pirates want to watch a crap copy of a movie that's in the theater and won't even wait for a DVD quality rip, never mind something better.
