The totally neutral theory has been around for a while. Every model can still be seen through its morphs tho. All the V4 characters I've seen still look like V4 underneath. Same is true for Genesis. Even though the goal with those figures is for the base mesh to be neutral. It doesnt matter which figure it is, just using them as an example since they're the most common. Obviously a more distinctive face will carry more of the base shape into the morphs than a less distinctive face, but once you get used to seeing the base on a regular basis, you'll almost always recognize it when you see it, no matter how morphed it gets - within the human realm of faces of course.
