In favor of Kodak, I sent out a roll of colour film to a local minilab, and got back terrible results. I looked for some answers and found that Kodak not only described the exact same effect, but had an explanation and work arrounds for the mini-lab operators and is phasing in a new version of their C-41 chemistry to avoid the problem. turns out that minlabs doing small valumes have more evaporation than carry-out and so the soup gets too strong. The new chemicals sidestep part of the problem, and they now tell the labs to top up with water rather than replenisher at the start of the day.
I am sure that there was a lot of expensive r&D time and many rolls of test film run though to get that fix in place.
