What does the painter want? You haven't been specific. Pearl adds a sophisticated sheen and is very popular finish for trim and doors. And frankly, it often requires that the painter buy a specific paint. My issue is when you are paying thousands of dollars for a painter and then they want to cheap out on the quality of paint - really a pet peeve since cheap paint doesn't last nearly as long nor wear as well as Benjamin Moore. When I specify paint I insist that the actual paint manufacturer's paint is used not just colour matched. Expensive paint is far cheaper then having the painter come back 2 or 3 years sooner.
