Anime stuff isn't part of the official, Manga canon.

Boruto's eye so far seems to look like an underdeveloped Byakugan, so i don't think it would expand the "three great". Also, since Kaguya basically showed that it's the two great Dojutsu, since Rinnegan and Sharingan were originally the same eye.
