Then you don’t have Prizm black lenses. That’s it’s. The difference in lenses has been a subject of discussion worth Oakley for decades. But mostly is affected by the iridium coating and not the base. Prizm has very little iridium compared to legacy and lens blanks with standard Prizm are made thousands at a time so It’s not common with Prizm base.
Prizm black on Left
Black Iridium on right
Very clearly rosey on the left
It says "Prizm P" on the lens and there is no other lens than PBP that it could be. If it isn't fake, from a trusted store.
