Ridges/Ripples on PP Rotors

[Megale96]

Had my Front Driver & Passenger rotors and pads replaced about 500 or less miles ago. There ere these ridges on the Rear Driver and Passenger side. I worked the brakes hard a few times and the Rear Passenger looks smooth again, however the Rear Driver does not.

Brakes were squeaking a bit before I worked the brakes a bit. Don't hear noise anymore.

Arent both rear brakes supposed to wear/rub the same way? E-brake was/not being used so that's not causing an issue.

FD= Front Driver
FP= Front Passenger
RD= Rear Driver
RP= Rear Passenger

Rear Pads & Rotors are original (car has about 9,500 miles) (Pads are still fairly thick)
Front Pads & Rotors (Replaced at about 9,000 miles)

Yes you should be getting even wear, Looks like a bit of corrosion on the rear's there, 1st thing I'd do is clean and re-grease the slide pins to ensure the calipers are free floating,
