I can understand that since they reworked everything through the graphic update things obviously will have small differences, diffuse textures having been modified, UV maps being changed, the 3D mesh as well... so the difference between pre DT and 7.0 makes sense to me. That they try to bring it closer to what it was before once 7.0 got feedback, as promised, also makes sense to me.
What doesn't make sense to me is that they fucked it up even more for 7.1 by squishing every eyebrow into an angry è_é face for every option by making them all identical in looks, completely losing not only the vibe difference of the old ones (including 7.0), but also the texture quality, because it's all squished now. It's a sloppy work.
