why does 5.6 have different colors than 5.4?

look very closely on the left is 5.6 its most noticeable on the rock texture, why does it look like that and how do i revert it?

Hello there @Quittzer!

There is a subtle difference, but its definitely noticeable. From what I could gather around the community, whenever you update the engine, it is possible that certain settings tied to color variance, rendering, and material values, are modified.

If possible, please send screenshots of the color values in your materials at the moment. Also, as a test, try switching the working color space in your scene, following the doc below (UE defaults to sRBG/REC709, check if that was changed as well):

here is a barn in both versions you can see in 5.6 its slightly brighter or pinker and heres both materials. the color ramp looks slightly different but i want to make sure its nothing else causing the issue first
