It's not just about 120Hz refresh, or current lack of 12 bpc displays. I'm on a soapbox about Apple offering HDMI 2.1 and it's 48gps I/O in the next AppleTV hardware device to extend it's useful lifespan.
Most newer TVs offering internal streaming apps and Roku/Firestick/etc devices are inexpensive. This puts the onus on the ATV to justify it's price point. IMO, doing that requires premium features including HDMI 2.1 so you get the best from your display, and your investment isn't obsoleted too quickly.
