Can a bat tester read if a bats been rolled?

i was thinking about getting my comp bat rolled cause all its does is break in the bat evenly instead of having cold spots on a bat. my league is now using a bat testing to check bats. do these machines tell if the bats have been shaved and rolled or just shaved? also what if u a don't fully roll it, maybe just barely roll it just to help get it going. and what about bats that are broken in. can they fail in the bat tester because the 98mph seal has been broken after continuous hits?
