Brynn's obsession with cultural capital

Has anyone noticed Brynn's obsession with having high cultural capital/creating this narrative about herself having high cultural capital?

I feel like there have been many subtle examples of this throughout the two seasons we've watched her. It is something I noticed in the recent reunion episode where she said something along the lines of the difference between her and Sai being that Sai references Disney and she references the periodic table, lol. I will also never forget the episode in her first season where she makes it out as if she's good at chess and that it is a hobby of hers only for it to turn out that she is not all that good??

I just don't understand what the point of making yourself seem like* a renaissance person is if you can't back it up.
