I think we are talking about CGI faces here and thats just not doable yet and this research won't change a thing about it.
The last movie I remember having a CG face was Clu in Tron Legacy which certainly was state of the art CG, unfortunately 'state of the art'[1] in face modeling/animation is just not perfect yet.[1] https://www.youtube.com/watch?v=CvaGd4KqlvQ

"The last movie I remember having a CG face was Clu" By strict definition if you remember it having a CG face then it wasn't good. It's not possible for you to remember a good CG face because if it's good you wouldn't know it was CG!
The next big test might by Paul Walker in Fast and Furious 7 or Philip Seymore Hoffman in Hunger Games 3. Both big budget movies where the actor died and CG will be used in at least some places. That's the ultimate. I think we can already get away with CG if the actor isn't known. But for actors who have faces we know and mannerisms we subconsciously recogonize it's another step up in difficulty.
