Vibrant Visuals: Brightness doesn't work correctly on some devices

The brightness setting doesn’t work correctly on some devices. Following the calibration process results in an extremely dark image, and increasing the brightness to compensate for that results in a bright, but washed out look.

Steps to reproduce:

1. Load into a world with vibrant visuals experiment enabled

2. Go into video options and click ‘vibrant visual options’

3. Click adjust brightness and drag the slider down to match the prompts you are given

4. Click continue and then press esc, and observe how the game is extremely dark despite matching the brightness prompts

5. Go back and move the slider up to compensate. Observe how the game now looks too washed out

Expected results:

The slider should work as intended and not cause the game to become either too dark or too washed out
