Its effectively impossible to get some streaming services to stream content >720p to a linux device. I know I tried several years ago to use Disney+ and could not find any way to get 1080p content, even on a windows machine. I think now they have an official windows store app, but still refuse to stream full HD or 4k content to a web browser.

More recently I've tried hbo max and it does the same thing. Could not get higher than 720p, even with chrome and whatever DRM options theoretically fix the problem.
