Thanks for reporting this. In UWP, MediaPlayer automatically figures out whether it can/should use HDR by looking at the monitor the CoreWindow is on. There is no CoreWindow in WinAppSDK apps so a different mechanism will be needed to communicate this information.

Was this fixed in Windows App SDK 1.5?
To be frank, I don't see a difference between WinUI 2 and WinUI 3 (or the Windows media player app) using a HDR10 video file on my HDR monitor.
