I'd check w/the manufacturer, but the pad material that is bedded on the rotor in the photo looks a bit odd, but not all that bad. Maybe a bit intermittent? Which pads are you using? My Pagid RS-19 (front) and RS-7 (rear) pads bed-in w/a good bluish-grey deposit that is very uniform around the rotor (stock M3 rotors).
What did you follow for a bed-in procedure? I'd contact the rotor mfr and send them the photo and get their feedback.
