there is no explanation to that. all c41 processes are equivalent, the main 
difference is that profi labs have smaller variation of brands, speed, etc, 
which translates into less variation of iodide/bromide content of 
in-service developer. that effect was detected for the first time with an 
introduction of Fuji 400 negs. They required different replenishment rate. 
it is my speculation, cos I honestly do not believe, there is any 
difference. If someone has an example, please post. Grain pattern is 
dependant of the film structure, not developer.
