It has been a learning curve for me.
The first HDR material I viewed on my LG B6 was streaming, and I was not just underwhelmed but confused about why anyone would prefer it to well done SDR material. It looked like video tape but I understood (and hoped) that at least some of the problem was my inexperience and certainly compression from streaming.
After spending some time adjusting the TV and getting to watch content via disks I am a believer. It does take some getting used to, but the additional detail is there, especially in deeper shots, and the color is just phenomenal. I am not saying that it equals the jump from VHS to DVD which to me, personally, was the big step up, or even that of DVD to Blu-ray but it is very impressive nonetheless, for it's own merits.
I have not had issues with bright highlights, I find that is part of the upgrade of HDR, but I get it that everyone is a bit different. Certainly there is a variation from disk to disk, and even scenes within the same disk, but in the opinion of my wife and myself, HDR/WCG presents a much more compelling visual than SDR. I hope if the 2016 LG OLEDS get only one more major upgrade it will be the tone mapping purportedly on the 2017s. No disrespect to the DD+/Atmos folks.
I have had some issues with my UHD player, and was toying with the idea of going back solely to 1080p disks for a few months, but after watching "Ghostbusters 2016" last night, my wife and I looked at each other and agreed that was NOT an option. HDR has not ruined SDR for us, we still enjoy well done 1080p content, but HDR is the frosting on the cake when done correctly. We will choose it every time from now on if the content allows it.
