Try only to fix RGB Balance errors, not luminance errors trying to follow the PQ HDR EOTF curve.
There is unaligh so when you try to fix specific pattern and adjust control which slighly affect that pattern then errors will be introduced.
The first step has to remain untouched and the second only +-1 max, the other have larger range but I don't remenber exactly because I don't own LG OLED, but when I calibrated there zero problems with real content, it took from me more time to verify various content from time to measure and do adjustments. You have to sacrifise a low dE to prevent error in real content.
Below is the post-calibration of a 65E6 in HDR10 mode which is not producing any problem visually:
Looking only the good dE charts is not enough, it requires to check various movies/scenes to check if the calibration settings are not introducing problem to picture.
A good approach to do this, is the following method I performed....For example, to compare and locate if the calibration adjustments are not introducing problems, lets say that you have used HDR Dark mode to calibrate RGB Balance.....copy the basic settings (OLED Light/Contrast/Brightness/Color/Sharpness/ColorSpace etc....) and all other enhancements disabled to HDR Bright.
So the only difference between HDR Dark vs. HDR Bright modes, it will be only the adjustments of White Balance the HDR Dark has. Bring the LG preset mode selection screen where with arrow key up -> ok -> arrow key down -> ok....you swap between these 2 modes.....Pause movie stills with various colors/shades and swap between these 2 memories to check that all are fine....with gradation and other artifacts.
