Something odd is that there's a paragraph on the Japanese and Chinese pages talking about their attempts to faithfully recreate the character visuals that's absent from the English one.

Machine translation:
Each race has its own unique production process. For example, in the creation of Hyuran males, it is important to convey a calm and friendly personality. In designing the textures for the characters' faces, we sought a natural finish that accentuates their personalities while avoiding excessive realism and flamboyant details and instead focusing on the style of the original work. In addition, in creating Lalafell, applying the same techniques as for the Hyuran male would have resulted in dark shadows on the face. For Lalafell, we adjusted the unevenness of the high polygon model repeatedly in ZBrush and weakened the NormalMap value to adjust the vertex normals of the face so that the shadows would not be too dark. This allows for an expression that brings out Lalafell's cuteness even more.
The promotional images have obviously been touched up, but they also look much loser to a high res ARR than the updates in DT.
