You're right in that most mixing seems to be at 48kHz. From what I've seen, though, the input (recording) stage would often sample at a higher rate (with a correspondingly easier analog anti-aliasing filter with a gentle roll-off, and then a non-causal digital decimation filter with a sharper roll-off would produce the final 48kHz "recorded" signal.
32-bit/96kHz is clearly pointless for the final product, but if you're doing a lot of manipulation and processing to produce that, doing that processing at higher resolution stops rounding errors from accumulating.
