Dysphoric transgender people don't flaunt what causes said dysphoria; I.E. exaggerated tits and child bearing hips, etc. The end result of a transgender person's goal is to present and pass as one's own desired sex in all aspects- physically, socially, and psychologically. Now I'm no expert on the topic, but that's what I've been able to conclude from resources online.
But couple that with both Rory's own identity of, "asexual non-dysphoric nonbinary girl" and these sloppy, overly-sexual caricature fetish "headcanons", and what I get is I don't think she quite understands the concept of transsexualism in and of itself.
In my opinion no, her "trans" Cap is non-dysphoric.
