Really interesting watching Planet Earth II on my parents' Samsung KS8000 vs. my Sony 930D, and how much better the HDR is on the 930D. The importance of peak brightness and local dimming is real. Definitely understand how 2017 and future models with higher peak brightness are going to further enhance the HDR picture. At the same time, it will be curious to see what the practical limits of brightness are, however, as a lot of scenes in Planet Earth II already do a number on my irises because of the rapid switching between light and dark scenes. As I've said before, movies will need to be mastered with this in mind, especially when transitioning between scenes, and I do think there's going to be a practical limit to brightness, even for small areas on-screen. Hopefully, we'll be able to get some additional contrast through better back levels on LCDs and hit a nice balancing point.
