If a Blue asks for a 747 UD seat map, it shouldn't show as available any seats that couldn't be paid for. But if a Gold asks for the same seat map, all of those seats should show as available. (Assuming, in both cases, that they're not actually occupied already.)
I don't think EF knows your status (KVS does, obviously). I seem to recall that when rows are blocked for Silver and Golds this shows as Blocked in EF and thus it's clear what is going in, but UD was an exception - the status / paid seating was only visible via BA.com.
