I've just assumed that the horns were probably lost due to breeding with humans.

Looking through all the leaked concept art (or rather, photos of concept art that was displayed at some exhibition), there's also a lot of artwork of Toneri's domain.

The relief and altar seem to have an eye motif, with a pupil that resembles a lotus flower (or the Divine Tree, which itself resembles a lotus flower). New dojutsu, or just symbolic? I guess we'll find out next week.
