For the HDR calibration, use a different color temp in SM and the regular menu.
The target colorspace is ST.2084 REC.2020 for HDR10.
For LG manual calibration see here:
Thank you for the assistance. Currently I am using Cool for SDR and Warm for HDR. I was able to pre-calibrate the SDR without issues.
But I am a little confused on the HDR WB calibration in the Service Menu. When performing the pre-calibration for the warm preset for HDR what would be the correct settings in ZRO? Would I be setting the color space to ST2084 Rec 2020 and Patch Scale to 8-bit Legal? Would I also be turning on the HDMI override to engage HDR10 as well at this point?
