I very much doubt it. I'm sure she's the sort of fan who's only interested in the seven core novels* and not in the Wizarding World as a whole universe. There's no Hermione in these franchise spinoffs, and some of them don't even take place at school, so I imagine there's little to hold her interest.I do wonder if she's been keeping up with the new things that have been put out in the Harry Potter franchise since the last movie, like the Cursed Child and the Fantastic Beasts movies.
*Question: Do we know whether Ruby ever actually read the Harry Potter books? Judging from her infatuation with Emma Watson's specific portrayal of Hermione, I almost get the feeling that her whole knowledge of HP comes from the movies.
