You are probably tired of hearing advice on this, but I will give you a less invasive (no service menu needed) option, assuming the calibrator doesn't use AutoCal and doesn't charge more to do this. It also assumes you are not using all your HDMI ports:
1) Use the Sure app and downgrade to 4.10.15. Calibrate one or more picture modes for SDR/HDR - Cinema, Technicolor, ISF Bright, ISF Dark on HDMI1.
2) Update the firmware to 4.10.55 and calibrate one or more picture modes for SDR/HDR - Cinema, Technicolor, ISF Bright, ISF Dark on HDMI2, 3, or 4.
Of course, use which ever HDMI ports you want - you might want the 4.10.55 calibration on HDMI2 if you are using ARC, etc.
) LG releases the gamma-corrected version, you can copy your Expert settings from the Step 1 HDMI port to the Step 2 HDMI port. This should work since someone reported (@Jk82?) that no changes to white balance were needed between 4.10.15 and 5.xx.xx and gamma was back to the way it was previously. If it never comes out, you can copy the step #2
HDMI port settings to the step #1
