I know it is/was very popular belief among fanfiction writers, but was it ever confirmed in Databook or any chapter of manga? As far as I know, it allows to see if someone else is under genjutsu by observing flow of chakra (like Hinata did in Sasuke Shinden)

And with whole destiny thing: I would say for now we have very little information about it. It may very well be just Momoshiki's ability and not power of Byakugan itself. Actually, Momoshiki has done this "fate reading" only with Byakugan activated. Moreover, he said that "with his power and eyes" he couldn't see his own fate, unlike Boruto's one.
