I scan images all the time, and quite often I come across an original whose colros are seriously degraded. 16 bits per channel is an absolute necessity here--so you can do some serious color shifting and processing, and still have a reasonably smooth tonal curve when you downsample to 8 bits per channel. If you try to do serious color corrections with 8-bit color channels, the result is usually banded so badly it's unusable.
I'm no professional, but I know enough to know that 8-bit color channels are only "good enough" when your colors are already just right--need tweak them much, and it's no longer adequate.
