Found this while rotating my tyres. Odd pattern right? Is this heat, or dead rotors? Aside from the discoloration there's no lip and they're within spec as far as thickness goes. Pattern exists on front rotors only. Discoloration exists on all four rotors.

Car is still parked in the shed.

High spots, and lots of heat.
If the brakes still operate smoothly, pretend you didn't see any of that and carry on.

Roger that.

Quality slotted rotors for 380's are cheap at the moment, how many km's have they done?

Not sure how many Km's on the rotors. May be original items.

I may look into the rotor+pad upgrade after I do tyres. The car is only doing about ten km's a week.
