Another thing is that HDRI doesn't like to play nicely with 3D motion blur and DOF (two commonly used elements in 3D movie FX). It has a tendency to slow the calculations dramatically, and the result is often lower quality and unpredictable... ie., flickering and pixel crawling/roping. You need extremely high settings to avoid problems, and in complex scenes, this can be taxing even on a massive render farm. That's why GI and HDRI are still faked most often for animation.
