Plasma 6: How to use HDR with games? (lemmy.world)

As the title asks, how does one actually use HDR for games after upgrading to Plasma 6?

This was the feature I was most excited about, and I can hit the HDR button on my display configuration and it looks like the desktop is going into HDR mode, but so far I have had zero luck enabling the HDR feature in games. Every game I've tried had the HDR toggle disabled with no way to enable it.

I am running these games under Proton and I've tried both 8-GE and 9 Beta. Any tips?

Edit: probably important to note that I am using an AMD GPU under Wayland

NVIDIA Latest Drivers:

file: /etc/modprobe.d/nvidia.conf

options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"

These can also be set under modprobe, but I was troubleshooting a while back and it was easier to edit them this way before booting. So here's my kernel parameters I have set:

nvidia-drm.modeset=1 nvidia-modeset.hdmi_deepcolor=1 nvidia-drm.fbdev=1 nvidia.NVreg_TemporaryFilePath=/var/tmp
