Thanks that was interesting he was very pragmatic. I agree with the 1000 nits goal, it seems enough for me but I suspect the folks with titles mastered at 4000 nits must be doing something different.
The area of HDR that has not been well address is the color space. There are brightness histograms and master resolution stats but not much on color.
Does the HDR grade preserve the P3 color space from the theatrical version?
I suspect there are titles where the color is degraded from the theatrical release.
For example, Star Wars the Last Jedi had much better reds and color in some scenes that lost all impact on the HDR version.
The splash of red against white sands is a good example. I made a mental note of how striking this looked in the theater.
At home, it was meh on the HDR and SDR version. The HDR and SDR appear more alike that other HDR titles.
The professional reviewer seemed not to notice that there was something lacking, rating this 4K quality at A?
The Black Panther is a reference title where the difference between HDR versus SDR is striking. All colors are bolder perhaps even more so than the cinema.
HDR color should look as good or better than the theatrical release. They are both P3 but HDR can provide increased brightness.
For me, the theatrical release is a baseline that HDR should be able to match or exceed.
