Something I haven't seen discussed at all is HDCP compliance.
Of course, games don't need that - I'd say that every game studio is aware that without streamers, you don't sell games, and streamers can't stream when HDCP gets in their way.
But for the use case of a home theater? PS4 and 5 as well as some Xbox varieties can do 4K Netflix [1], no issues. Installing Windows, I'd guess that's fine too. But Steam OS? Nope. Anything too "open" gets the boot, including Android if you dare root your device, Widevine L1 refuses to work as the TEE doesn't reveal the keys if it detects an unlocked bootloader.
