Windows 10 in-game brightness/gamma issue

I just did a fresh install of Windows 10 x64 Pro (I previously ran Windows 7 x64). Everything is great until I launch a game. I play Amnesia the Dark Descent which is a very dark game so I know what true black looks like, and for me in Windows 10 the black
isnt black, its grey, which seems to be cause by gamma or brightness being too high. I ran the Windows calibration tool but it doesnt help as on the desktop brightness and gamma are normal, its only in game where it is wrong.

I have tried updating drivers, rolling them back, messing with brightness and gamma in the nVidia control panel but nothing is solving this problem and I cant seem to find anyone else who has experienced it. I have a nVidia GTX 670 with latest drivers.
