HDR settings

I am wondering about HDR settings.
I got a new alienware AW2725DF OLED screen. Enabled 10bit colors in nvidia, HDR in windows and msfs - and it looks good. But - night sky are dotten with a lot of dark greyish points other than stars.
It seems that turning off hdr in the seem makes raven dark.

How is this set up correctly?
