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)
