4K content/format is simply not needed today in the vast majority of homes - 99%. Most people do not have the screen size/viewing distance necessary to see ANY difference between 2K and 4K. Many barely have the screen size/viewing distance to see any big difference between 480i and 1080p(i, or 720p).
Though, I can see some value for 4K 3D content/format, where you get a full 1080P picture for each eye.
Some people claim to see noticeable differences on 1080P content using a 4K projector versus a normal 2K projector. While I don't doubt they see a difference, I think people are misunderstanding what's truly happening.
I would wager the difference you have is higher quality optics, better focus and electronics, and scaling in the 4K projector. The true comparison would have to be similar 2K and 4K projectors as possible.
Here's an interesting article dealing why 2K is inferior to 4K for digital cinema presentations.
