ACEScg Working Color Space renders more saturated than previous versions

Regression: Tested in UE5/Release-5.0, this issue does not occur so this is a regression.

This appears to be effecting all Working Color Spaces as well. Each Working Color Space chosen renders the scene completely differently then how it would render in 5.0.

1. Create a new project
2. In Project Settings, set Working Color Space to ACES AP1 / ACEScg
3. Restart the editor

Actual Result: Level renders at a much higher saturation when Working Color Space is set to ACES AP1 / ACEScg when compared to 5.0

Expected Result: Saturation should not change between sRGB / Rec709 and ACES AP1 / ACEScg
