Megascans Snow assets are BEIGE in color with a default SkyAtmosphere - WHY?

I’ve built my Landscape scene and tweaked my environment lighting so everything looks great.
I go to add some Megascans Snow assets (Snow Embankments) and their color renders as beige.
After 8 hours of debugging, I figured out it’s the SkyAtmosphere causing the issue.

Mind you - it’s settings are DEFAULT values. When I delete it from my scene, the Snow asset colors look closer to what they should be. I drop a new default SkyAtmosphere back into the scene and the Snow asset colors revert back to beige. (see screenshots below)

How do I resolve this without messing up my Environment Lighting??
