Color Rendition not the same between Paper2D in Editor and PIE versus Standalone Game and Blank Project

There is a fairly noticeable difference in color rendition between a 2D Side Scroller Paper2D project when in Editor or PIE compared to Standalone Game or the same sprite asset in a Blank UE4 Project, given the same Post Process Settings.

1. Open a 2D Side Scroller Project with No Starter Content
2. Play as Standalone Game

RESULTS: Standalone Game's color appear washed out and desaturated compared to appearance in PIE or in Editor.

EXPECTED: Appearance in Editor, PIE and Standalone Game should be identical.
