I know this is the big burning question. Without having any inside knowledge of any Calman fixes and or changes to the 3D LUT creation process I can only report what I experienced testing the beta which I was very fortunate to have the opportunity to do. I calibrated five 2019s so far and I did find doing a point based 3D LUT corrected CMS issues that I was unable to resolve with the CMS controls or a matrix LUT. Because of time constraints, I've done several 1,300 pt and 3,000 pt 3D LUTs and used Ted's color ramp patterns to look at the results. On the 2019 LGs with CM 2019, there is still some slight banding in the very dark blue area of the pattern BUT it is very very slight. I needed to put my glasses on and look right up to the panel to see it. This compared to doing the same on a C8 with CM 2018 where it was very easy to see banding in the blue-magenta areas of the test pattern.
So I don't know if the improvement i'm seeing is because of CM or LG or a combination of both but I was very pleased to see improvement to the point where although I would like to see a perfect result, the result is very good even though if I looked hard enough I could barely see banding in the test pattern and there was no way I could see it with content.
Now I'm using a Klein profiled to a Jeti with the recommended pattern insertion delays, etc and also making sure no patches are left on the screen during LUT calculations which I believe is fixed in the RC version, so your results may differ since there are all kind of things that can effect the result with these OLEDs. Also i'm sure there will be users with those "magic" eyes who will stare at specific content instead of watching it and claim there is a problem. I believe work is being done on CM to make the 3D LUT perfect and will probably see results of that work in a subsequent release.
Overall, I felt CM 2019 in the configuration I use, worked very well without issue for SDR, HDR and DV picture mode calibrations. As I've stated before I feel the new HDR calibration with the custom tone mapping made a visible positive change when calibrating HDR since now you are able to measure the peak luminance of your specific panel after the native 20 pt calibration and recreate and load new tone maps for 1,000, 4,000, and 10,000 nits or your own specific one to the set. It fixed the problem that D-Nice found where the set deviated from the EOTF curve making the picture look overly bright and too saturated and improves near black and overall detail.
I'm very busy at the store so I won't have an opportunity to do any additional experimenting but I hope my observations help.
