bais yakov maidel: Women gain the reward for Torah learning through their husband and children. Doesn’t apply to other accomplishments.
I believe the story regarding R’ Ahron goes like this: A man who taught in a girl’s high school told R’ Ahron that some of his students are very learned. Does he have to give additional kovod to these girls. He answered, even if she knows every rambam (or whatever) etc, doesn’t make her a talmid chochom. And therefore, he doesn’t have to give additional kovod (like standing up for her).
According to the book “Halichos Bas Yisrael”, one must give additional kovod for the wife of a talmid chochom. It also states that there are those who say one must stand up for a learned women as well.
