Checking what kind of improvements from last year UHDTV. I know this year will be able to stream 4k from built in Apps from Netflix and maybe Amazon. Wondering more about picture quality using 2d as that is where most of these tvs will still be used. I've heard about high dynamic range and closer to rec. 2020 but not sure how this will help broadcast hd or even blu ray. Please post any comments here as I and others would like more information from people here that are more knowledgeable than I.
