HDR is currently experimental.

Red Hat is working on getting it integrated, and Valve have it in their display manager.

But for general users, out of the box, no.

Funny that SGI some 20 years ago supported more than 32bpp.

It's far from being ready, but as usually Valve is making the most progress: https://wiki.archlinux.org/title/HDR_monitor_support

It's in progress, but it's one of very few sacrifices you make. Anti-cheat is really the only other one of note, and many games are now supporting anti-cheat on Linux.

There’s no AutoHDR at all, so yeah.

FWIW, desktop Windows 10 HDR is broken too.
