However, maybe there really are two case: Pure Byakugan are awakened from birth while "impure" byakugan needs to be awakened by the person. Note that Himawari doesn't have the regular white eyes either.

As to people going on about Gentle fist techniques: Remember that one of narutos god-powers was an intuitive understanding of chakra and techniques. Boruto inherited that (he's a prodigy after all) but Himawari might have that as well, and so intuitively understands how to use Gentle fist. After all, people have an intuitive understanding of how to fight yet there's so much to improve through the various martial arts
