It looks like the base obj meshes were exported at subdivision 1. They have 200k vertices, meaning they don't match up to base Genesis 9 @ 50k. One thing I tried which seems to have semi worked is I used Blender to un-subdivide the mesh and then imported that. I am uncertain whether or not the morphs themselves were HD, because if they were, then that would mean un-subdividing gets rid of a lot of intended detail
