Scanning B&W silver based film almost certainly does not come out neutral,
because of the Callier effect - the scattering of light due to solid grains
of silver. Conversion to grayscale, via standard conversion or channel
mixing is definitely required.

I certainly misinterpreted if that's the case, but even still, B&W film is
rarely perfectly neutral. T-Max in particular has a habit of coming out
bright purple.
