This was also explored near the tail end of 1.0 (the events that lead to the calamity cutscene) and I believe during the Coil storyline as well. There's been numerous other hints here and there that there's little difference between the Twelve and the primals.

At this point, there's plenty of evidence to suggest they are the same, and little to no evidence that they are not. The sole difference appears to be that humanity has not been tempered by their gods, and do not try to summon them... with the events of the Calamity and two attempts now to summon Rhalgr being the exception.
