I see what you are looking at, but like gregincal it looks to me as if something dark is being reflected in the chrome trim at that point making the top of the chrome trim appear lower than it really is. That particular relfection happens to end right at the gap, but you can see more reflections in the chrome trim at other spots along its length (in particular one happens just in front of that gap, but it ends before it reaches the gap) that could fool the eye to make the height of the trim appear shorter or taller than it really is if you didn't see it as a reflection.
There is also a bright lens reflection spot right on the point of the trim right inside that gap there that makes it hard to gauge alignment of the "fold" in the chrome trim.
(And the smaller version embedded in the post makes it harder to see this - I opened the image in a new tab by itself and the full size makes the reflection/shadow more obvious and you can almost make out where the top of the trim really is...)
