Anyway, I'm looking forward to your test. It would be great if you could test it connected to a LG OLED with PC mode enabled.
Don't use You-Tube because re-encodes any video you will upload, it's expanding the Video to PC Levels also (adding errors also), so it's impossible to see ant WTW...the digital levels will be changed and will not provide the same accuracy with the original encoded content.
For example in this ChromaPure 4-Point Amplitude Chapter you can find 100% Saturation with 100% Stimulus or 100% Saturation with 75% Stimulus patterns but I'm not suggesting to use them as reference since you-tube has tweaked them during re-encoding.
You-Tube has expand the video levels to PC levels, for example 100% White is 255, and not 235 as the original file I uploaded, also youtube re-encoding added their own signature to RGB Triplets.
100% Red was 235.16.16 and it became 233.0.2 and supposed to be 255.0.0 after expanding video -> data levels.
100% Green was 16.235.16 and it became 20.255.9 and supposed to be 0.255.0 after expanding video -> data levels.
100% Blue was 16.16.235 and it became 3.0.245 and supposed to be 0.0.255 after expanding video -> data levels.
100% Yellow was 235.235.26 and it became 252.255.10 and supposed to be 255.255.0 after expanding video -> data levels.
100% Cyan was 16.235.235 and it became 22.255.253 and supposed to be 0.255.255 after expanding video -> data levels.
100% Magenta was 235.16.235 and it became 235.0.246 and supposed to be 255.0.255 after expanding video -> data levels.
The same issue with incorrect levels the Advanced Brightness Pattern has, I recommend only to view it for 'demo/sample' reason, not based to this pattern to do any adjustment.
