Nice work! RE Village has very similar resultsI took a look at the Resident Evil 4 remake demo. Previous games have had kinda poor HDR settings in the sense that following the instructions often didn't give you your displays proper nit brightness in game. This is my first time doing this so consider it very basic. I started by taking several HDR screenshots at various points throughout the demo using a fixed HDR setting in various states of scene brightness in the demo and was able to determine through that a consistent value for the brightest highlight. After that I found a spot that gave that value and proceeded to take HDR screenshots of it using each of the 21 points you can set using the Max Brightness slider. Then using the HDR + WCG Image Viewer I was able to measure the peak nit brightness of each screenshot.
Going through each of the 21 captures I was able to produce this chart:
I did this out of my own curiosity and impatience, hopefully it'll be useful to anyone!
