It may be circumstantial but I just checked and Netflix and Disney+ are both only rendering at 720p in Linux (Kubuntu 26.04) in Firefox and Chromium for me. Maybe official chrome is better, I don’t have it installed at the moment.

The trouble you’ll quickly run into is that with a non-iOS/Android/Windows platform your streaming sites won’t go above 720p, and your attempts to run sandboxed Android apps will pretty much all fail. Now if all you mainly do is serve local content from e.g. Jellyfin that’s not much of a problem, but as you already own an AppleTV that’s probably not your only use case.
