The reason ICE doesn't work with silver films is that silver is opaque
to infrared, unlike dye films.  ICE basically works by scanning with
an IR channel, to which dust is opaque and the dye layers are not, and
effectively creating a mask.  Since silver is opaque, the image is treated
as a dust and removed.

It has nothing to do with the scanner actually recreating the grain.
