Alya in your picture is a lightly 2 shaded anime with extremely complex round eyes a style used in many waifu anime before like Denpa Onna to Seishun Otoko. And yes Violet Evergarden.Wistoria also falls int this category.

Violet Evergarden being a lightly 2 shaded show with complex eyes exactly like Denpa Onna, Wistoria and Alya san

Godeater is actually was 4 shaded in some scenes so I'll give you that.
Oushitsu Kyoushi Heine I haven't seen but from youtube it seems that you're right.
