LG 2018/2019 Template for DeviceControl Interface is now available for Free to LightSpace users. Its ready a lot of time ago, and a lot of users currently using it.
The page where you submit to request access has not been updated to talk for LG 2019 release yet, but its planned to be updated when complete Guide for LG OLED Profiling for LightSpace will be released. (working on it)
The procedure is exact same as for LG 2018 Template.
Current DeviceControl Interface users, if they will refresh their Cloud, they will see the LG 2019 Template available, but see how to receive the update there: How to receive the latest LG Template Update for DeviceControl Interface.
You can see very detailed instructions about how to request free access, how to setup setup and connect your LG OLED TV using LG 2018/2019 Templates for DeviceControl Interface here: https://displaycalibrations.com
If there interest about B9, it may added instantly, but generally people prefer to invest no other LG 2018/2019 models and not to B8/B9 models.
LG C8/E8/G8/W8/C9/E9/G9/W9 OLED TV's have (33-Point Cube 3D LUT) while the LG B8/B9 has the standard version (17-Point Cube 3D LUT) of this technology.
The number of color points that can be stored is about 7.3 times greater on the LG C8/E8/G8/W8/C9/E9/G9/W9 (35937) vs B8/B9 (4913).
The LG C8/E8/G8/W8/C9/E9/G9/W9 OLED TV's advantage of having more color data points in the 3D LUT is that there are then fewer interpolated points between adjacent calibrated points compared to LG B8/B9.
This allows more accurate interpolation, fewer quantization errors, and better output value continuity at the calibrated data points, which yields fewer image artifacts and smoother color gradients in the rendered image.
Additionally, LG C8/E8/G8/W8/C9/E9/G9/W9 OLED TV's users will be able use larger patchsets from the 'standard' 17-Point Cube (4913 color points), like 21-Point Cube (9261 color points) which can provide better final results.
