Hi. It's hard to say without an example file, but normal maps typically do require UVs (especially if textured). If you're using height to normal VOP to apply procedural noise as bump, UVs aren't required since the tangent frame between height to normal and normal map nodes are consistent. If you're wiring 3d noise directly into normal map node, then discontinuity artifacts and other issues are expected.

My guess would be that the auto-generated texture cache for XPU from earlier version is stale but it's still being picked up by the new version, so whatever color management policy change that happened between the versions isn't being reflected in the new renders.
Can you try removing all auto-generated .rat files (should be where your .exr files are by default) and see if there's any change in behaviour?

Hi. This bug is addressed in the upcoming daily build.
