If the situation is still the same in 6 months' time it would be different, but it's just too soon.
The truth is that LG is not the first company which offering a consumer model with 3D LUT uploading, its the second company, since you can upload already an 66-Point 3D LUT (287496 Color Points) to Panasonic EZ1000 for SDR and HDR10. Much larger 3D LUT Cube size from LGs 33-Point (35937 Points) where it has 3D LUT for SDR only. Panasonic released at 2017 and its the same model for 2018 also (it hasn't replaced), its a monitor installed to many post-production houses as client view (not mastering monitor).
Panasonic has open format, you can use whatever software you like (which export Davinci Resolve cube file format 3D LUTs), just you save the table to an SD card and you upload to the TV, so you have backup to your hands, while you can use CalMAN or LightSpace....freedom for all....to use whatever meter/pattern generator/software each one has.
This is what all companies have to do....give freedom to user to use whatever he has, not add a feature which is locked to specific software only.
LG has locked that 3D LUT upload feature to CalMAN users only, there a lot of users which are using already DisplayCAL or LightSpace, it will be good idea if LG will give an open-format support, to specify a file format which will accept and give the capability to the user to use any software he prefers for cube generation, exact the same what Panasonic is doing already.
LG has to provide a free utility to upload or export from inside the display the 1D/3D LUT tables, so the users to use whatever software they want (free or the one they have already bought, the one they are more familiar with already and satisfied).
Also export feature is useful for those who don't have their own meters, when the pro calibrator they will hire will generate/upload the 1D/3D LUT tables to the TV, to be able to keep backup these correction tables from any problem during future firmware update or reset to factory defaults of the display (from normal menu), to be able to upload again the correction tables to the display again.
For DDC of internal calibration controls, Panasonic has already out a free application anyone can download for iOs
where you can DDC using a iPhone/iPad etc.
Panasonic EZ1000 is calibration software agnostic, you just save the 1D/3D LUT to an SD card and you upload it to the display.
If LG can provide a LUT upload utility and describe what LUT format it will need then it will be possible to use other software for 1D/3D LUT generation, like DisplayCAL/ArgyllCMS/LightSpace since only an upload will be required, no other connection with TV.
It's something users have to start asking LG directly about this... for the users to have plenty of options for any pocket.
LG has to be more flexible, this will increase their panel sales also because thousand of users are using free manual cal or other display characterization solutions already.
LightIllusion would be happy to work with LG to provide working 3D LUT calibration. Light Illusion have spoken to LG, but so far the required information has not been provided.
LG would need to provide necessary information to Light Illusion to enable direct access to the 3D LUTs within the display, as LightSpace already has for many displays, such as the Dolby professional monitors (as used for Dolby Vision HDR grading), Canon professional monitors, FSI (Flanders Scientific Inc.) displays, Eizo, NEC, Konvision, BON, Craltech, Kroma, TVlogic, etc... (See: https://www.lightillusion.com/partners.html
But if LG release stand-alone utility, the LUT format LG is using internally is already supported by current LightSpace (3dl file with 33-Point Cube and 12bit values), once LG will provide an upload utility, it will require only to export and upload internally to the display from current LightSpace version.
