Disney's transformation of their non-White princesses

Has Disney transformed their non-White princesses within the time period between 1995 and 2016? If so, why do you consider this a transformation? This does not have to be an “either or.” You must use these two princesses as the key examples, but you can draw comparisons to other non-White princesses where you see fit (although there are not many). Please include information about the narrative, characters, and themes of both Pocahontas and Moana.
