Every pose is an example of the race's unique emotes, hence being labeled 'unique'. They are all in game.

The only one of the Final Fantasy MMOs that had unique creation poses was XI, but in there they were meant to convey the 'feel' of the character and were actually an editable in-line cutscene. XIV uses the game engine and stock emotes. Try the emotes listed in this thread, you'll see.
