That was never definitively confirmed. I’ll tell you why I personally don’t believe it, and that’s because when he fought against the other replicants, they all beat him to a pulp. He would’ve had their equal strength, especially if he was a law enforcement officer (after all, if Daryl Hannah’s Pris, the “Pleasure Model”, was that powerful, it wouldn’t make sense if a cop wasn’t).

The implication was that he would have been from the new line of even more human-like replicants, like Rachel, since he seemed to have false memories like she did. So there’s really no telling if he would have had the same “specs” as the Nexus Six models. The new replicants weren’t supposed to know that they were any different from humans, and if they had superhuman strength, that would be a dead giveaway.
