Estradiol (bioidentical) does this as well, it’s not a limitation of just premarin. I have two cones so I would know! You need progesterone generally to get rounder boobs (it promotes the growth of the milk ducts, E just promotes growth of the breast tissue itself).
Now also, as a disclaimer, what I just said about cones and prog is partially anecdotal; prog hasn’t been studied all that much yet, but quite a few transfems report cone boobs until they start prog (I will be starting it within a few months <3).
I think that tracks, the horse estrogen would have been good enough for estrogenic effects but bioidentical estrogen does better to trigger effects along the whole endocrine line. I know when my estrogen is in good levels it effects my progesterone cycle (in a good way) and progesterone in turn is commonly used to help round out breasts after tanner 4/5
Trans women thought it gave them cone boobs, that was the gossip back in the trans group back in the day.
Lara Croft is a trans woman, cmv.

I’ve never heard of taking estradiol resulting in more prog
