The texture is set up a bit differently on valkyr, metallics area aren't 100% metalics, it's about 97%, which looked better in render I had, but doesn't look that good ingame. I will probably update the files change that.
About Khora, I think it's already fixed, and for Wukong the issue has been reported and should be fixed soon.
Sadly, I don't think the Khora spikes are completely fixed on the Mithra skin. The ones on her blouse tails still revert to the regular Khora spikes in missions, and if you cycle through the spikes in Arsenal.
A screengrab of the reverted spikes under the spoiler.
