Steps to reproduce:

1. Open File > Build Profiles

2. Create a build profile and add player settings to it (press Customize Player Settings)

3. Change the Color Gamut value under Other Settings > Rendering

Actual results: Changing the color gamut value on build profile changes the value in Project Settings' player settings and vice versa.

Expected results: Value should be changed per build profile

Heads up that color gamut only shows up for platforms that supports it (such as OSX)
