OLED 4K TV is the real deal and you are going to want it.

I got a chance to take a close look at both the Sony and Panasonic engineering sample 4K organic light-emitting diode (OLED) TVs. They have the best color reproduction I've ever seen on a television.
Of course, there's also the "other" 4K technology: Edge-lit LED LCDs. I saw some of those at CES too, and they're nice, but... they have all the usual LCD problems. That is to say they're hard to watch unless you're pretty much facing the TV straight on and the contrast ratios aren't anything to write home about.
OLED, on the other hand, is far better to watch no matter what your angle is to the screen and the contrasts are the best thing I've seen since high-end, picture-tube TV start disappearing from the marketplace. In a word, it's gorgeous.
even ordinary Blu-Ray, thanks to OLED's great dynamic contrast, look great.
I know this all sounds like way too much money for way too little. Trust me, this isn't like 3D TV, where the reality hasn't lived up to the hype. Like HDTV before it, OLED 4K TV is the real deal and you are going to want it.
Here is what Broadcom CEO said about 4K TVs in interview with EETimes :
EE Times: Could you explain why almost every UHDTV demo on the show floor was about snow-covered mountains, Swiss villages and lazy rivers meandering through green valleys? I saw only one video clip showing a soccer match, in which the images of players were crisp but the movement of the ball strangely a little jerky.
Samueli: [laughs] It’s probably because the demo is using footage based on 24 frames per second. You need 60 frames per second to show fast moving action in sports on 4k x 2k TV. The bit rate to screen is not fast enough either. Current HDMI cable handles only 24 frames per second.
EE Times: So, we are waiting for HDMI 2.0?
Samueli: Yes. You need to upgrade your connectivity to HDMI 2.0. The spec designed to handle the higher frame rates is already done and available. You will see HDMI 2.0-compliant chips available within a year. I see these as startup issues that will get sorted out over time.
I know you all love OLED screens but don't hold your breath for 4K TVs yet.
