Not sure how useful this will be but i am going to post it anyway. I think i am finally settling in on C9 calibration... Keep in mind that this is varies from set to set and just in case, my 65 inch C9 was manufactured in March 2020.
Stock TV condition: Awful GREEN push in all modes SDR, HDR, Dolby Vision...
Colorimeter: X-Rite i1Display Pro
Pattern Generator: iTPG(C9 Internal Pattern Generator) at first, then MadVR TPG using PC connected via HDMI.
Goal: Accuracy
Lessons learned:
1. CalMAN Home for LG Autocal -> not reliable... this together with OLED sets not being very stable is a bad combo. Better use manual calibration if possible and double and triple check with actual content... it's very likely that something is going to be fucked when using Autocal. Also questionable 3D LUT generation by CalMAN software, fucked me up more than once... Ended up just using TV controls and adjusting White Balance and CMS for all modes manually.
2. Really warm up your TV before doing calibration. Some pattern with rotating colors for a few minutes at least, maybe episode of a favorite tv show.
3. Do not attempt calibration until your total tv usage is at least 100-150 hours after unpacking or be ready to verify/re-calibrate after about this much time.
4. Had a glitch at first when after just turning TV on it would be stuck at standard or eco mode even if proper calibrated mode is selected in menu... until any video content is played. I think C9 boots into mode that is selected for Set-Top Box/TV source( even if i don't have one ) and it messes things up.

After Calibration something like that can be achieved:
PS. If you feel like your C9 is pushing green might be useful to try these... 2 Point WB might be enough to correct most errors. Dolby Vision can be properly calibrated only by uploading config file generated by CalMAN but i would still apply 2P WB to it even if there is no config available, i see the same green push in it as in HDR10 content, so WB adjustment should be identical.
