Do you plan on keeping the kit or re-selling it if you bought it? If you keep it, it is your choice what to do...If you plan to re-sell it, leave that decision of removing the wrap to the buyer...
As idrum4fun states, you should be able to tell by looking down on the bearing edge whether there is another wrap underneath...If there is, I would keep the kit and I wouldn`t remove the BP wrap either...
Cheers
