From the manufacturer

It’s been a long-time since we’ve tested a ball like the Proof. A ball that looked great for everyone regardless of style and bowlers all over the world have confirmed this. While the Proof is known as a great ball, we are excited to follow it up with the Proof Pearl, a shiny version that gives you the same great reaction, that’s intended for more medium oil lane conditions.
