>but VP9 support is absent (or not exposed in many common Linux paths) so YouTube is sloppy [...] but YouTube 4K is generally VP9 or AV1 rather than HEVC

I installed linux yesterday. Youtube doesn't let you backtrack to VP9 in the user profile setting. It serves AV1 by default now for all resolutions. Bummer if you're on older and/or low end hardware.

Maybe some browser extensions can force VP9?

I believe h264-ify still does. And many of the fancy "remake YouTube to not suck" extensions do as well.

To h264 yes, but not to VP9, no?

Yup, the name is a bit of a misnomer at this point: https://addons.mozilla.org/en-US/android/addon/enhanced-h264...

What you really do is disallow everything save vp9...
