That wear pattern is fascinating. Why are the unworn parts unworn? Which type of shape/flexibility allows that?
Seems like screws holding the plank do a very good job locally, but the suction keeps flexing the rest of the plank - resulting in such wear patterns. Looks like a tiny bit of rake is still there, judging from front edge wear, but it also looks like the rake is there (only) for suspension and leaving enough room for rear dampers to, ugh, damp.
As for the floor, these new angles indeed might be showing us a reverse depression in the floor, although at first to me it looked like a lot of different "fillets" resulting in such shading. This depression could potentially be beneficial for bouncing, acting like some kind of pressure-damper when the ride height is at its minimum. However, such depression would certainly come at a cost of overall floor downforce.
