All factory ammo has sealed primers to keep oil or gun cleaner from getting to the primers and deadening them. The sealant is sometimes colored, but more often is clear.
Factories tumble rifle cases to remove the annealing color before loading, not after. I was not aware they tumbled loaded ammo, but if they do, what is seen here could be caused by speeding up production and not waiting until the primer sealant dried before tumbling.
