I've seen 4K and have never really been impressed. But HDR is different. The demos I saw at CEDIA made me a believer. HDR is a big improvement, IMO. It's almost like seeing an HDTV for the first time. You really don't need to see a side-by-side to know that it's a huge upgrade. Will anyone be upgrading their gear for HDR or any of the other new video improvements?
