They are getting closer, but I do agree that it is still not quite there. It's pretty common practice now at the beginning of each film production to do full image capture of all of the main talent. It's a back up in case something untoward happens that the film can still be finished by using their 3D likeness.
More commonly for postproduction fixes (think stunts and inserting talent likeness, relighting/reframing a shot, inserting reflections when CG-ing the background of a window etc.…) so you can fix sequences without having to recall talent which can produce availability delays and additional expense beyond what it takes to fix digitally.
