I think this is a bit controversial, I read in some book (maybe it was Lawrence? Or Bergen? Or Hamman? I don't remember) that transfer...3NT should show specifically 5332, allowing opener to pass even with 3-card support with some 4333 hands. I also recall a discussion on this forum about one top pair (I think it was Hamman-Soloway) that had a way to show specifically 5M332 after partner's 2NT opening, for the same reason.
FWIW I am in favour of the minor showing some slam interest or (at most) severe doubt about 3NT. It seems somewhat perverse to stubbornly describe distribution and leave partner to guess about slam potential.
