4K Needs More Than Just Resolution

“Broadcasters know consumers can barely see the difference between HD and 4K if you do nothing more than change the resolution, and this is well based in solid trials methodology. It isn’t just a bit of prejudice. The higher numbers are good for marketing, but not much else,” said Paul Grey, director of European research for NPD DisplaySearch.

For the new format to make a real difference, improvements other than a higher resolution are needed, including higher frame rates, better color reproduction and a higher dynamic range for brighter whites and deeper blacks, according to Grey.

The second paragraph is the key to me (I'm assuming the first paragraph to be true, that it's hard to tell HD from 4K when only resolution is changed). I'm not so concerned with higher frame rates, but better color space, bit depth, and dynamic range are areas that need some iteration. I would be more than happy with 24fps (or 30) at HD with better color, and dynamic range than the current craze of bigger resolutions that we can't actually deliver. The press to 4K seems like little more than marketing at this point to me (save for the rare benefit that you can (1) show it in its original resolution on a screen that benefits from it, (2) do pan & scan in post for mastering to HD).
