Those are generally being used on much smaller productions, or at least "simpler" fidelity things (i.e. non-photo CG animation like Blizzards's Overwatch). So for Pixar/Dreamworks style things (look great, but not photo-real) they're useable and provide a definite benefit in terms of iteration time for lookdev artists and lighters, but it's not there yet in terms of high-end rendering at scale.
