Plasma 6 has officially been released, with it comes partial HDR support:

Plasma on Wayland now has partial support for High Dynamic Range (HDR). On supported monitors and software, this will provide you with richer and deeper colors for your games, videos, and visual creations.

Set an ICC profile for each screen individually and Plasma will adjust the colors accordingly. Applications are still limited to the sRGB color space, but we are working on increasing the number of supported color spaces soon.

To improve Plasma’s accessibility, we added support for color blindness correction filters. This helps with protanopia, deuteranopia or tritanopia.

I will be exploring it with AOC Q27G3XMN. I hope this thread can be a good place to discuss HDR on Linux and maybe make a difference in it’s progress.

HDR core functionality support is coming along nicely but ease of use is still not good. HDR (through Plasma desktop) has still not been released for average users. I came across this guide that may be helpful: Guide to non-steam HDR Gaming on KDE Plasma 6.2

If you need to know more, maybe get into colour profiles and such, one of developers (of HDR) has a blog which will be a good resource.

If you’re new to Linux please be aware that there among Linux OSes there are fixed releases and rolling releases. Rolling release OSes have update approach similar to Windows, where as fixed release will remain with version of software that was shipped at the time it was released and there won’t be another fixed release until two-three years later. While you can always manually update your fixed release OS, for a beginner it can be difficult to understand what software you’re lacking or/and need to achieve something. For example you may want to enable HDR but then you may require various developer packages/software, that you as a end user do not know of and consequently enabling of HDR will end up in failure. This is a distinction that is important to know as a beginner to Linux.

Also on Linux there are various ways to play/configure games; buy and play on Steam or configure it yourself with a compatibility manager/launcher (Lutris, Heroic, Legendary, Bottles etc). The guide I linked to above shows you how to get HDR going outside of Steam.
