Describe the Bug

After installing the latest Radeon Software 25.10.2 all the white color look like horror when HDR is enabled in Moonlight. And when I toggle HDR off in Windows during streaming everything starts to look washed out in addition. If the HDR was set to off in Windows before streaming is started everything is fine regardless the Moonlight settings.
I suppose this has got something to do with AMF 1.5.0 that came with that version since everything was great on Radeon Software 25.9.1.
The only setting I ever touched in Sunshine is UPnP. I set it to enabled.

Steps to reproduce:

• Update host to AMD Software 25.10.2
• Enable HDR in Windows
• Enable HDR in Moolight.
• Start streaming in HEVC or AV1.

P.S. My client device has an SDR display, I enable HDR in Moonlight so I don't have to switch it in Windows each time.

That might be a hardware issue with my specific device (Framework Laptop 13 AMD with 2,8k display).
Here is why I think so.
I will try to test it further later.
