On most recent Plasma (KDE) I can confirm HDR also just works (tested on AMD). I do miss a contrast slider though, SDR titles seem a little bit bright.
Of course Nvidia didn’t port “RTX HDR” yet. They’re preoccupied fixing their driver mess by building a completely new one (NVK), so for the foreseeable future it’s still better to run AMD with Linux.
