I don't think the dynamic range of chromogenic B&W is nearly as great as silver B&W. Note that since both chromo and silver B&W is film, it is 'wet darkroom' until the scanning stage. Its true that 'Zone System' includes the work done on the print itself, but the goal of Zone System printing is to have a negative that has enough contrast range to be printed 'straight' on #2 or #3 grade paper. So IOW the neg manipulation techniques: (monochromatic filtering for improved MTF of the lens), Push/pull exposure/dev, all are very useful tools in generating a negative that scans well - with greater 'captured' dynamic range and sharpness than either from CN films or color that has been either 'desaturated' or channel selected for B&W conversion.

The dynamic range (tolerance) of color film is great, and can be pretty effective if you stretch the contrast in digital processing. I do like the quality of the contrast of my C-41 B&W scanned and manipulated digitally. If you print the unmodified scanned image, it is indeed very flat.
