That's because she is a demi-elemental, i.e. an elemental race that was always a monster. Only the elemental races that started out as non-monsters (namely the four main elementals) and form covenants can gain dark forms.

The odd one out is the dark matter. They were always monsters but are basically dark elementals by default, and they can also form covenants.
