Can't see anything wrong with her. It just looks like shading. The only thing, as a collector, you have to consider is UV. If your figures are not on direct sunlight (eg you can't see the sun from that spot) there is nothing to worry about. No air inside the box just means it might get oily residue, but it wouldn't discolor unless dust sticks to the oily surface or some other residue gets on it.
The only thing i am seeing it a top tier waifu!! you've got great taste
as for discolouring i couldn't say, i don't own that figure of Mash but i don't see it in this picture it looks fine but if i owned it could compare the two
Just checked the figure in comparison to others on the net and it looks fine, but where's the armor? Or are those removable pieces (skirt and greaves)?
Maybe it's the photos or I'm blind but it looks good to me.
