Your wording suggests a large number of retailers, and thus far I've seen maybe one (though I don't pay much attention to any nurseries that don't specialize in CP's, and they mislabel just about everything anyway). And my plant is definitely glabrous overall save for the pitchers to a small extent, and I've never seen a ventrata in any conditions with leaves that broad, not young or etiolated or any other condition; one trait it carries when immature like that is ventricosa's narrower leaves. Granted however, the only way we're ever going to tell is when the plant matures, and one thing it does have riding for it with that possibility is the very small wings on the pitchers.
Also, technically for the name "Gentle," it was never officially registered so any plant that anyone wants could be coined with the moniker regardless which was given it first, and for that matter it could have been a grex from which multiple different looking clones arose, hence why there are several plants with the title that clearly have fusca parentage that look distinctly different from each other.
