What is your braking technique? Do you use regen? Are those marks deep or barely there?
Looking at the inner circle of the brake surface, it seems worn to me from heavy braking
My p3d has one third of your mileage and my rotors look new but I use regen almost exclusively
Would be helpful to get a picture of the brake pad material too, don’t know if you can get your phone/camera inside the wheel spokes to get a decent snap?

I mostly rely on regenerative braking, rarely touch the brake pedal.

Could be a number of things then as suggested, I guess it will all become clear at the service center. Please keep us updated and best of luck-hope it’s a warranty issue
