What you are seeing is actually quite normal, every car from different manufacturers I have owned all have the same break disc wear profile. It is how you see how the disc is wearing in terms of thickness. The deeper the lip the brake disc wear is higher. Looking at both pics again closer, there is a difference left to right, the lip is still correct but have noticed the wear to the outer edge being what seems half inch down the disc. Where the pads replaced 2k ago along with the discs? The left one could be the pad is not seated correctly or the guide pins where not cleaned correctly so the caliper is not floating correctly. Did they use BMW pads or after market? It could be pad face never bedded in correctly.

Don't worry.
