Its not a matter of gamma settings, everybody is experiencing this "problem" (which is not really one, more like an artistic choice but i really dont like it). I've been chatting with someone on steam which has found a solution to disable it, but it doesn't seem to work with me unfortunately
I'm gonna post his "solution" anyways :

there are some comparative screenshots now, thats a great thing.
another detailled report i found :
"Something is broken as mentioned, not sure what setting it could be though. When I first started the game up it looked normal but when I went into the settings I realized that the SSAO was only set to medium resolution so I changed it to high and restarted. And now the game loads with the haze mentioned, and the overlay itself isn't black as it should be. Resetting the game to it's default settings doesn't help either.
Interestingly enough, the menu graphics are not affected by this issue. And when you first start up the game after loading you can notice starts out normally before the haze overtakes the image."
