I would suggest a mini-PC running Linux and Plasma Bigscreen instead of an AppleTV if you want something 100% private and user-controlled.

my priority for a TV isn't privacy or user control, it's minimizing annoyance. and appletv, roku, or similar streaming boxes delivers that best.

Unless you're using streaming services like Netflix, in which case you're stuck with 720p because of widevine.

Do you recommend any specific distro for this?

[drnick1]

Arch or Fedora, because you want a very recent KDE version.
