In principle, BD will not match from within *A. Since you are UA Gold, you will have all the *G benefits and, as blue plus, you will also get the front of the plane+free catering. So, all you are not getting by not being matched is the 35% elite bonus, so it is not the end of the world, imo. Just build up your status by crediting to BD, using your UA*G card for lounge access for now. That will enable you to partake in the complaining of how awful the DUB lounge is.

BTW, you can no longer fly to Paris with BD.
