I am confused by your use of the term stratification. If you're saying that the beer somehow settles into layers with different densities, I don't think this is happening. If you're referring to the fact that beer changes flavors as yeast, hops, and trub settle out, yes that is true.
If you use a CFC, I also believe it is possible to have differing levels of bitterness and hop aroma if you split the batch into multiple fermenters, if your beer has any late hop additions.
