I've decided that has to be a seam, not the paint. There's not enough space in the A-pillar for an upper door frame. And if there is, this is seriously reworked from the H3 (or it's lost in the shadow).
Then how would zip out windows work? Perhaps there is a thin frame that runs from the door, around the "window frame", and back into the door into which one would zip the window.
Ugh, I'm bored. Can you tell?
