Barrel finish.. problem?

Hey guys. I picked up my M&P 40 today and cleaned it right when I got home. I didn't pay attention before I cleaned it but is this normal?



The finish on the crown is splotchy. I wonder if my bore cleaner did this. I used Blue Wonder gun cleaner.

There's no residue left on the gun. It's clean indeed but the finish on the crown is light in color.
I'm not worried about it too much. It's all cosmetic. I was just wondering why the crown was almost silver in color instead of black. No biggie. Looks better on the business end.
