There is no difference between amateur and professional Kodachrome. Same 
film. Simply aged differently before sending it to the store.

Professional labeled film, E6 or K14, is aged at the factory to an exact 
point, then shipped. Refrigeration at the store maintains this "age" so 
professional photographers are buying a known color rendition/balance.

Amateur labeled film is not aged by the factory. It is sent directly to the 
store and ages while it sits on the shelf, or not if it is used right away. 
The color rendition/balance is not a stable factor.

So why would someone separate out film "labeled" professional from that 
"labeled" amateur and process them at vastly different times? Many many 
professional photographers buy and use amateur labeled film. There are many 
photo jobs that do not require an exact color rendition over time. Amateur 
labeled film is cheaper. But exactly the same film. Off the same 
manufacturing machine. At the same time.

You are paying for Kodak/Fuji/Agfa/etc. to "hold" the film when you buy 
"pro" labeled film.
