Hi, my os- win11, gpu - Asrock AMD rx 7800xt challenger oc, Monitor- acer nitro vg271u m3
I enabled HDR in windows 11, in game and in monitor's OSD settings. this issue happening each game which supports HDR natively (not auto hdr). The issue is- during fullscreen gaming whenever i alt tab and focus to other apps instead the game window or if i run the game in windowed mode , the in game colors gets more vibrant (guessing this is actually HDR getting enabled?) but when i just run the game fullscreen the colors gets less vibrant (guessing this is actually HDR getting disabled?).
Showing a video of this, u can see when i alt tab the game goes more vibrant -

I'm providing Dxdiag result for display - and screenshot from windows settings -> system -> display -> advanced display

I like the more vribrant one quality. How do i solve this issue? my windows and gpu drivers are upto date.
i know my monitor's hdr is bad, but some games like throne and liberty, enlisted, naraka bladepoint etc looking actually awsome in HDR (when its working properly like in windowed mode) and way better than SDR . So for specific those game i want to fix this issue so that my HDR dont get washed out when i play those games in fullscreen.
