POV is not the same as "person." 1st person & 2nd person pretty much define POV, but third person does not.
It is even possible, although rare, to have a first person story where the Pov Is not that of the narrator. An "as told to" story can do this "Then he told me that he went to the movies, and there he met..." Occasionally a 'sidekick" story can do this, like Dr Watson for Sherlock Holmes, but even more so. But normally a first person story has the first person as PoV character.
The complex PoV changes in Vinge's
A Deepness in the Sky are part of its attraction, for me. And then there are unreliable narrators.
