Time for the big reveal! Took me a couple of nights, but I finally got HDR calibrated to reference standards. Use Technicolor expert. Leave all the main settings at default and turn off all the picture enhancement features, except dynamic tone mapping. I personally turn it on after my calibration.
White balance: warm 2
2 point high: red 2, green -1, blue-8
(This will vary depending on the set, though it's very similar on the two sets I've owned)
Code values rgb
All values after are affected by tone mapping and can't be calibrated from my experience.
Color management(only change luminance)
Note: Red has changed a lot since the update. Not sure why....
Game mode uses color temp of w50 and color of 70
You want graphs? Here are the luminance and rgb level graphs from the Technicolor calibration.
Please, LG, do not change the firmware and make us all go through this again!
Enjoy my fellow enthusiasts
