"Good news for owners of 2019 LG WOLED's that use ColourSpace/LightSpace. You can now easily and freely (manually) calibrate Dolby Vision/HDR using the built in iTPG of the TV controlled directly by ColourSpace/LightSpace with the latest version of the Device Control Template for 2019 LG OLED's."

It is worth following the thread to get a full overview of DV HDR calibration of LG WOLEDs.

We have just tested a 2020 CX model, and it appears to work in exactly the same way...

We tested LUT Upload, as well as the iTPG.
All appears to work exactly the same as the 2019 models.
