Manley thinks they have done it accidentally, or even as collateral, when removing the landing leg from that side.
I don't think it'll buff out, but it won't cost too much to replace.
The more I look at this the more likely I think they'll use it for the inflight abort. They've probably got enough old stock still sitting around it'll become a little mishmash of old and new parts which they'll blow up.
Also, that Dodd said that this was the second flight of the new COPV in the second stage, so it's going to be interesting if this counts against or if adding a redundant hydraulic pump resets the launch count for the "frozen" design.
