Pointed ears are predominantly associated with animals, especially felids, this may be a hint for a possible genetic connection.
I do not, however, ever remember even a hint that there would be any benefits related to or arising out of this, however marginal it be.
To the science side of the things, elongated - if not pointy - ears seem to be associated with hearing into the ultrasound range.
It may however just be the "be different - think different" thing.
