OK, I see it.
They just took the area around the mast and stitched it together. It’s really hard to notice, but it’s clear that the deck of the lander is cut off in the corner.
It’s in a studio in Burbank.
Well, there is a full scale mock-up somewhere, isn’t there? Can come in handy.
What’s the blurry black rectangle?
It looks like the panorama pf photos they stitched together missed a spot.
