Steps to reproduce:

1. Open the attached project
2. Open and play 'ColorTest' scene
3. Notice the movie texture colors are not correct (blues seems to be lighter while all others - darker) compared to a simple texture (simple texture is on the left side of the game view, movie texture - on the right)

Note: Tried opening png/mp4/ogg files outside Unity editor, everything looks the same with other video players (see the screenshot for comparison).
