Pixar does not use 100% GI because (at least right now, with computing resources costing what they do) it's not cost effective for them to use maximum quality techniques when they can be faked and save literally millions of dollars in computation time.  All the big dog renderers actually have compositing features built in to allow individual objects to accept or emit GI (and pretty much every other effect) on a selective basis.

i was listening to a podcast where they said that they are not using it because they can not control it.
