Probably not. The amount of PoW distribution in Ethereum is quite small compared to the ICO. The "initial distribution" effects discussed at the above link are dominated by the ICO.
Vitalik reserved an obscene amount of coins out of the premine for himself. He dumped a quarter of his stash but still dominates the rich list. Whatever POW whales own is nothing compared to what he still owns. Moreover, I doubt any of the ICO buyers own as many coins as Vitalik still has. The "initial distribution" effects are dominated by Vitalik's stash.
