I appears to me that someone applied something after several years of service. That ridge line that is about 5/8" away from the hat riser appears that it could be formed by something being behind it. Like as if there was a heavy dirt collection there when painted. Then maybe sometime later the dirt and most of the riser disappeared, leaving this ridge. All this from a thirty second evaluation. It seems possible. Never seen those colors in factory painted cowls.
Looked again, missed putty in the first look. Had to enlarge pic. All appears to be aftermarket. But you should be pleased with conditions.
