That's what you SAY, but you haven't provided a specific example.  
We've repeatedly asked you to give us objective support for what 
you're saying - but all you offer is gedanken experiments and 
hypothetical situations.  If what you're saying is true you ought to 
be able to provide concrete evidence of it.

Remember, your EYE doesn't reconstruct the spectral distribution of 
a scene either because it also relies on just 3 overlapping 
photopigments.   

If what you're saying is true it ought to be a piece of cake to 
identify a color that comes out with a noticably different density 
compared to some reference color when scanned from black and white 
versus color film.
