Well, if you want to be pedantic, "dynamic range" (DNR) is not about white and black, it means the ratio of the largest/smallest values of a changeable quantity. This can be sound, it can be light, it can be a neuron response. The bits of a color component give you how many finite pieces you can slice up the range into. An encoding (linear/exponential/etc) give you a projection from that bit representation into the range of reconstructed values. My general point is, it's not purely about the # of bits, it's also about the range and projection function used. But yes, you are right about the other stuff. But I'm not concerned about what can be achieved with real physical display panels today. I was talking about idealism, not incrementalism, I want to look at a display and almost not notice it's there, like looking through window on my wall. is Rec 2020 going to get us there?

You're asking for something that nobody is prepared to deliver, and nobody has plans for delivering it, and nobody knows what kind of technology would even be used to create such an experience. 1. Natural contrast ratios are so far beyond the limits of current display technology that it would take a complete revolution in material science just to figure out what to make the actual screen out of. 2. Natural colors are have a gamut that cannot be reproduced using the fixed primary model. You would have to do something like put a dynamically tunable laser inside each pixel. It's like asking for a USB port on your computer in 1949. However, if you're prepared to make some small compromises: 1. Okay, contrast ratios are limited by glare from ambient light. 2. Okay, we'll use three primaries: red, green, and blue. THEN, Rec. 2020 is what you want. > "dynamic range" (DNR) is not about white and black, it means the ratio of the largest/smallest values of a changeable quantity. In the context of displays, the changeable quantity is the amount of light. White is the name of the largest value, black is the name of the smallest value.
