IMO, for the most part; the notion of the pointing lab is nothing more than smoke and mirrors used by some lab breeders to sell some pups. Marketing hype. I say for the most part because I've spoken to some lab breeders that make some pretty hefty claims regarding their dogs and I haven't verified it.
My brother is in the process is getting a dog from Sauk River Retreivers...

We'll see how it comes out.
Personally, I could never live with a labs anyways, pointing or flushing; so I just couldn't see myself getting on the bandwagon. I'll wait for the Elhew English Flushers to come out.
Good luck
