You can use the LG Template to manage/upload the LUT's to your LG 2019 TV, see how you can setup/create account there:
There you will see what to do before your start any measurement:

About patch generation, after many testing from very experienced LG OLED users of LightSpace, the best patch generation option is to use RGB 16-255 patches for the 3D LUT profiling.
Using RGB 16-255 patches will provide better results than from using YCbCr (16-235) or RGB (16-235).
To realized how amazing is the processing internally to the TV, if you use RGB 16-255 patches for profiling and use YCbCr (16-235) for verification, you get better post verification results than from using YCbCr (16-235) for patch generation and YCbCr (16-235) for verification).
For that reason, as the Lumagen PRO generated (slight non-bit-perfect RGB-Video) but can't generate RGB Video Extended (16-255) patches, you will use PGenerator for patch generation, configuring PGenerator to output 1080p24 RGB-Full and from LightSpace Options use patch scale 16-255. That setting combo will generate bit-perfect 16-255 RGB patch generation.
You will not perform any 1D LUT profiling, for the problems of 1D LUT processing explained here
You will start by enabling the calibration from LG Template of DeviceControl to upload a UNITY 3D LUT table to the Picture mode you like while you will feed the TV with SDR signal from your HDMI Input, for the TV to understand that you want to upload SDR 3D LUT.
Then you will disable the calibration from LG Template and you will set gamma of LG to 2.2 selection (its the selection which LG processing will not add any gamma offeset) and use Contrast/Brightness patterns to check your near black and for keeping headroom to your above 100% White.
You can see why you need to leave 'headroom' there
, with some picture examples of 'out of video legal range values' using 'Mission Impossible - Fallout Blu-Ray' movie as example there
Next step is to pre-calibrate your 109% White using ideally the SM White balance controls, for example select 'Cool' in SM (which will affect 'Cool' selection of normal menu') set values of RGB-gains to 192.192.192 (which preserve maximum panel dynamic range) and then reduce only 2 color channels to fix your RGB balance while with OLED Light you will adjust to have at the end calibrated 121 nits.
So since you will select from LightSpace 255.255.255 patch for that, which will display 109% White (10% window patches use), if will provide you 100 nits calibrated to your 100% white after the end of the profiling (and 121 nits to 109% Super White).
For meter settings you can use AIO mode with 0.75 integration, intelligent integrator 1, 0.35 stabilization of black frame, 0.5 sec extra delay, as the expect users which have posted to LG 3D LUT with LightSpace thread have used with great results.
Then you perform the 3D LUT profiling, generate a colorspace conversion for REC.709 and then export the DeviceControl 33p Cube file format, to upload with LG Template.
