does this account for rigid/nonflat surfaces? it seems like irl when the chocolate wrapper wraps the surface is smooth, but how would you model a rigid surface with a foil wrapper?

One thing that I think is interesting to note is distortion. At the center of the image (face/front of body) but as you move out, it gets more distorted (gloves/had/hat top/pants/back of body).
I think this is because the face/front of body is relatively flat, and it curves around the hat/side of the body, so flatness in the 3d model looks normalish but big curves look distorted in the texture image.

@alexkassil Interesting to note that even if we are projecting the globe onto a map, where every part is equally "relatively flat", there tends to be more distortion on the edges than near the center, as seen through Tissot's indicatrix.
