At first glance, I don't think she's been updated extensively. At most, it looks like they might have increased the resolution of her hair texture and nothing else. They most certainly haven't touched her face mesh, which looks just as low poly as before -- or her normal map, which looks just as flat. But I believe the devs have said that past unique NPCs would not be high priority, so I'm not really surprised. Ryne, in particular, doesn't call for it as much as, say, an NPC like
Varis, who has all the facial nuance and articulation of an ARR-era Primal. So, it may be a while before we can start using these characters as basis for comparison.
