3D widgets appearing overexposed when playing in level

This is my 3D widget in my BP

This is how it appears in the level

My level contains no lighting of post process

Does anyone know why this may be happening?

Found the fix here: Browser 3D widget looks washed out. - #3 by anonymous_user_8fd11f73

The default material outputs SRGB whereas 3DWidget expects Linear RGB, thus this issue.
