It's really wild what they've done to so many of our lip shapes, and this face is definitely one of the most egregious examples.
In general, this face looks much softer and rounder than it used to, because they removed the painted contour of the cheekbones and under-eye creases from the previous diffuse map without compensating for the change in either the mesh or the normal map (the texture that fakes a lot of the topography we see under different lighting conditions). Before the update, face 2 for male Elezen was the option you might've chosen if you wanted a less gaunt but still conventionally handsome, masculine face -- but the opposite is true now lol. It's very telling.
