I say this with all respect, it's just a supposition... I wonder if some observers just aren't good at seeing ripples and deformities in sheet metal? I remember these tests in school when I was a kid where they would show you geometric shapes, and rotate them all these different ways, and you were supposed to pick the proper one, rotated a different way. Some people did well on them, others just didn't see it.
Sort of like how certain people are really good at body work (car repair) because they can see and feel deformities, other people aren't good at it and can't tell if something's tweaked slightly.
To my eyes, the thing is clearly bent, yet several people in several comments don't seem to see anything. Every picture of the patch I've seen shows the metal is clearly bent. Whether it was distorted when installed, or distorted after some hard landings may be arguable, but it's hard for me to ignore my eyes and suppose that it's a trick of light... in every photo... on only that 1 panel...
