Nope, unfortunately you won't be able to tell without talking to that player/someone else who is friends with them. The info would be in the game files, but they are not easily accessible on a kindle.

Generally though people wouldn't have 5 new collection items on their wishlist for long. It is possible they have emptied their list on purpose. A large number of my friends do that. They don't want anything but are still playing and enjoy giving. Or they are only playing occasionally, so have emptied the list to so friends don't lose gifts if their gift box fills. Some active players do seem to slow down between updates, particularly those that have already completed all the quests in the game so don't have as much to do between new content being released.
