assuming fixed temperature and time, the only variable is CD replenishment.

I am not aware of any 3rd party stuff being worse than Kodak, Fuji, Agfa, 
Konica, the only problem would be with small pack kits from independent 
manufacturers (that sort that suppose to process both paper and negs in one 
soup).
I have official formulae for C41/AP70/Fuji with methods to analyse 
processing solutions, from major manufacturers. The only difference may be 
with sequestering agent. The rest: CD4, carbonate, sulfite, bromide, 
hydroxylamine, iodide are the same.

that's true, but affects handling (dirt, scratches), sometimes films are 
underdeveloped due to under-replenishment or faulty machine. The same may 
happen to profi lab.
