HDR values in Forza Motorsport do not save properly

Whats up with HDR?

So i noticed there is something wrong with HDR.

HDR works and HDR looks good, but for some odd reason if i restart the game, every time i have to re-apply the settings otherwise the view looks washed out a little bit, like gamma applied.

As example, i have set my brightness to 430. If i open the game, i have to turn in brightness settings to any value i want - save and then select the correct value. This happens every time.

HDR settings in the user config file located in %LOCALAPPDATA%\Microsoft.ForzaMotorsport\User_SteamLocalStorageDirectory\ConnectedStorage\ForzaUserConfigSelections are saved but despite that initially when i launch the game, every time the screen is somewhat brighter, like gamma setting is higher. So i have to do the following mentioned above: change value from 430 to any lets say 420, save and change back to 430.

Has anyone had/have this issue? is there a way to report this bug? so far i havent found bugs thread.
