I try to calibrate the UHD profil of my OLED 55C6. I use your OLED LG pattern test with a spyder 4 and colorHCFR. I have difficulties with the balance of RGB for some patterns. Especially those with high values. For example, with the 653 pattern, my RGB balance is pretty perfect (nothing to touch) but with the 637 pattern, the result is awful : Blue at 109% and Red at 95%. If I try some modifications on Red and Blue, nothing happened.
Before I start to search the problem with my spyder or the colorhcfr, i want to be sure your patterns is perfect and nothing goes wrong with them.
The patterns are ok. The issue you're probably seeing is the alignment of the 20-point white balance controls to their intended pattern.
Try looking at say the pattern for control point 606, set it the matching control point to +50 red -50 green and blue. Does it change color? If it's not a strong change, if it changes at all, then you have an alignment issue. This would mean you might need to use control point 591 or 622 to adjust a 606 pattern.
You can lower contrast a little bit until it gets aligned to fix this alignment (so 606 controls adjust a 606 pattern).
I've discovered a minor a bug with contrast and white balance controls. Changing contrast does not align white balance controls UNTIL either dynamic contrast is toggles on/off, or white balance controls are touched again (+1 then -1 forces it to realign).
You can simply turn the display off and back on as well.
This makes it a little tedious to adjust alignment via the +50 -50 trick described above.
This was a major headache for me and I only recently discovered this behavior on my E6. I'm assuming it happens on others, but no one has checked this out yet.
