Just as a matter of interest what brand monitor do you use.

I use a Dell Ultra HDR and also have a LG HDR monitor.
The Dell has the HDR checkbox in the Display Settings.

But the LG needed me to enable HDR using the kscreen-doctor command.
No idea why it claimed the HDR was not disabled and not check box to enable it.
kscreen-doctor is telling me HDR is enabled as well.
I issued the command to enable HDR on my monitor via sudo and the command failed. I'm not sure whether it was my monitor or KDE. As shown in the output with the failure kscreen-doctor also did not exit, I had to use ctrl-c to exit.

sudo kscreen-doctor output.HDMI-A-1.hdr.enable
[sudo] password for steve:
org.kde.kscreen: Failed to request backend: "org.freedesktop.DBus.Error.NameHasNoOwner" : "Could not activate remote peer 'org.kde.KScreen': startup job failed"
kscreen.doctor: Invalid config.

^C


Interestingly issuing the command without sudo exited without any messages.
kscreen-doctor output.HDMI-A-1.hdr.enable

You do need to run it as your user.  It needs to talk to the user dbus.
