The spectral sensitization and the colour filters within a camera film (if there any filters aside of the yellow one) are to split the scene luminance into three overlapping parts representing the primaries. As do the external seperation filters.

In general the sensitization of colour films in the past differed from that of b&w films. As the external filtration did mirror this there should have been a difference between colour films and b&w films exposed in succession through external filters.

But I am speaking in general terms. I can't see any typical Kodachrome look due to this.
