I have a HDR capable 4K display on my Dell XPS 9575 laptop but cannot get the HDR option to show in KDE Plasma settings. The settings show “Built-in Screen” rather than the monitor model etc. Does this prevent KDE Plasma from showing the HDR option? Do I need to configure the monitor further, and if so how do I do that? I can’t find anything recent that tells me.
Manjaro KDE Plasma 6.3.6 running Wayland

Mod edit (scotty65): formatted inxi output to something more easily read by removing the single backticks from each line and adding 3 backticks ``` to the lines before and after the full output
