The entirety of personal computer viewing doesn't have enough users where the media companies can't ignore them.

Fundamentally higher resolution playback happens on platforms like Windows and MacOS because they have closed, signed driver stacks, same as anti-cheat in games. Not because of the browser. So it will only ever happen if someone forks Linux to a more restricted, closed browser stack and offers that as a product (which is basically how a cable set-top box works in practice).
