We bring you two revealing screenshots taken straight from So Totally Versailles! - special double episode (S6E25,26). Marathon takes visual quality of their Season 6 backgrounds seriously as you can tell from the bottom screenshot, the same goes for spies´s animations in the top one. One additional layer of shading was added to the spies´s necks and belts. Overall quality and look are very close to TS The Movie! and Season 5 anatomy.
Thanks to our user Ilmira for posting these.
