Weird. Mine does not look like that. It's only a guess but, is your monitor using HDR? Because that might be the reason as to why the game would look like that. Using HDR tends to make games that don't support it properly look off (though in my case, the rpg maker mv games would look dimmer than it should).
Try this and see if it works. Otherwise, I don't know what can help besides maybe turning off HDR or setting its brightness.
