I'm sure they did somewhere in Endwalker actually, quality control took a nose dive. For me the deal breaker was the ungodly amount of repeating textures in Labyrinthos and a whole cave with literally nothing but repeating textures. I saw some islands in ultima thule flickering in the background...
In DT I just see texture stretching, things not lining up that would be obvious had ONE person did a quick walk through the area. I wouldn't be surprised if alot of AI might be integrated into their work.
