That's correct. Neither ROC nor VueScans "Restore colors" options
need the infrared channel.

VueScan also analyzes the grain patterns to find the grain
colors, but also does some clever processing to handle
different gammas in each dye color (each dye fades
differently when exposed to heat, light and humidity).
