Austin, I have no idea whether you are right about inkjet prints actually being ABLE to discern the tones better, but I can imagine it being a whole lot EASIER to maximize the mediums ability, at least once one is starting with a good workflow. Matching a negative to the built-in contrast curves of silver papers can be a mighty feat. I think the advantage, in terms of linearity, would have to go to inkjet, but one wonders IF one really worked to calibrate the wet process, to match the paper and development to the negative, if it's analog con-tone advantage wouldn't win the day... Just thinking out loud. I know I'll never have the energy to test it for myself. ;-) Ultimately, it's the whole gestalt of the process that has one prefer one over another anyway, I suppose.
