As we speak, people are working on the taxanomic status of the different niloticus populations. At the CSG meeting last year there was talk of the possibility that there may even be two separate species of Niles based on genetics evidence. We'll just have to wait till all the work is completed and the evidence is conclusive. I know several subspecies have been proposed and considered valid by some.
As for morphological differences in populations, I'm not sure. I believe Madagascar populations tend to be smaller as adults than mainland populations. But again, I'm not sure of this.
