In-game black color turns completely grey with noise after HDR10 is turned ON. Main menu black color is fine tho, only in-game one have a problem. Sometimes in expiditions, that weird noise can grow bigger and fill the whole screen.
Noise looking like static or film grain effect, it's always persist on grey (ex-black) in-game colors, with a chance to fill a screen, but, when it's not filling it, it stays only on blacks.
