Does AMS 2 fully supports HDR?

I have an HDR monitor. When I compare the high contrast values of iRacing in HDR vs AMS 2 it's very flat. I even increased the expose to 2.0 to see if it would make any difference and properly show the constrate range of HDR, with no luck. Then, I realized perhaps, AMS 2 (or the madness engine) doesn't support HDR.

Does anyone know? (BTW, you can't search HDR in this forum, the search engine needs more than 3 characters to perform a search )

 

I would like to know this as well
