No it is pretty even actually. The flywheel looks like it has hot spots almost opposite eachother. But with that much heat into the parts it is really hard to tell anything except that it got real hot.

By the time you get that much heat into the parts, the metal moves around a lot. When the metal gets hot, it expands so the spots that are the hottest rise which makes them contact the disc more so they get more heat which makes them expand and rise, etc. When it cools the metal contracts. If you were to place a straight edge on the what looks like the hottest spots, they are actually lowest spots now. If you run it again, those same spots won't even touch and other spots will become the hot spots.
