I'll say it again, it's not the yeast. Or it shouldn't be. haze is not the goal with these beers, it's just a byproduct of the process of making them. It's a byproduct of when the hops are added, and the quantity of them.
I've used a couple different yeasts with my NEIPAs, all of which have no problems dropping out clear. The conan strain I use drops out crystal clear in a blonde ale with no finings or gelatin if you leave it in primary for the full two weeks to clean up. But the NEIPA I make with it is hazy because of other items.
Yes, a small amount of yeast remains in solution in most beers, but not enough to cloud it. The few of these NEIPAs that I have bottled have had no more yeast drop out after carbing than any other style, and the kegs never have an over abundance at the bottom. The goal is not to make the cloudiest, haziest beer possible, it's to make a beer that's loaded with taste and aroma from your chosen hop variety. The haze just comes with it.
As mentioned other styles are different. Wheat beers are usually cloudy because of the abundance of wheat in the grain bill.
