When you have enthusiasts, hobbyists like those who would inhabit a place like this checking out 4K content on big projected images and saying there's little to no difference, how in the world will
this be sold to average consumers? At least they could immediately see a difference between a flat screen and their old tube sets, then between HD and DVD, and then, easily between 3D and 2D (even if they didn't
care for 3D). But this...it seems like there's going to be a lot of salesmen having to take the "who are you going to believe, me that 4K looks clearly better and worth your upgrade money, or your lying eyes?"
I dunno. Well, coke has been successfully re-marketing the same drink for a hundred years, so perhaps with enough effort they can pull if off.
Sorry, as an enthusiast about this stuff I'm feeling more cynical about so much effort going into a new standard that realism councils me to expect little benefit. (Which is why I'd be MUCH more enthusiastic about great strides in areas like contrast).
