Up to a point. The precise agents used and solvent action of a dev can make a 
huge difference to grain. EG TriX or HP5 can be absolutely marvellous in deep 
tanks, as they accumulate a higher concentration of sulphite and halide. It's 
virtually impossible to match this in one-shot processing. I have tried 
modifying several developers by adding sodium sulphite and HC110 in particular 
gave much reduced grain using it.

It seems unlikely that all C41 devs use the same dev agents or solvent content, 
so some variation in grain would seem quite rational, to me.
