This is still an issue in the newest update: 13.0.3105.58
I did find that if I go to the Video settings and use the "Use software decoding with TrueTheater enhancements" and the put it back to the default: "Enable hardware acceleration decoding whenever possibale" it then looks correct or gets rid of the contrast bump. You have to do it each time you play something though. Again I can run 12 on the same PC and it don't do this. It would be cool if they fixed it and put the mouse wheel forward/backward the old correct way.
