New GTX4090 HDR Support on Linux?

Hello all,

after I bought a GTX4090 and can now finally enjoy super cool graphics, I was wondering how it is about HDR support for Linux? You can’t really read anything about it, everything is already several years old. What is the status of HDR?

NVIDIA-SMI 530.41.03 (Ubuntu Repository)
Kernel 5.19.0-45-generic
cat /etc/X11/xorg.conf.d/20-nvidia.conf                                                                                                           130 ↵
Section "OutputClass"
    Identifier  "nvidia"
    MatchDriver "nvidia-drm"
    Driver      "nvidia"
    Option "TripleBuffer" "True"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
    Option "metamodes" "5120x1440 { ForceFullCompositionPipeline = On }"

Thanks and Best Regards :)
