I'm not disconnecting from the mains. My computer power supply and motherboard do trickle feed power, at least enough power to drive the mouse and blueray usb device I have connected.

The test I'm suggesting required your unplug from the mains.
The trickle power will keep state in the monitor and pc that can break hdr.

Why do I say this?

Because I proved to Dell that one of their monitors had bad firmware that only once triggered
in the bad mode would only reset on a cold power up.

When I get a moment o investigate I will have a look at EDID and see if there is where the HDR
info if returned from the monitor. I have not looked at that level of details yet, so things to learn about.
