In HDR calibration I used RGB 16-235 2160p24 10bit patterns with pattern generator because the HDR movie playback source that that setup was X-Box One S which is output only RGB 16-235 2160p24 10bit at it's output when it's playback HDR movies.
BTW I used my calibration disk and ColorChecker Classic (+Primary/Secondary Colors) Chapter with DVDO AVLab TPG Color Checker function (where it displays the digital level of the selected pixel on screen) to measure it's pattern output for digital errors when you playback a blu-ray, here are the results:
In 3D LUT Calibration with eeColor I used 1080p24 4:4:4 for patch generation because the customer player was bit-perfect only at that mode, when I analyzed it's output for digital errors.
eeColor 3D LUT Box can provide you amazing final results for SDR for a real reference picture performance since LG's are covering 100% of REC.709 and will provide you same kind of color fidelity the colorist/DOP/director saw during the mastering because they used 3D LUT there also.
For example Dolby Monitor has 2x slots of 65-Point Cube, same cube size like eeColor.
I have used LightSpace Software for 3D LUT correction generation using 21-Point Cube size (9.261 color point measurements) with LG 65E6 and CalMAN at the end only for verification, not because LightSpace don't have verification, but I wanted to crosscheck the final results with other software solution also.
BTW I have scalled the Luminance error chart from +-50 default range to +-10, to show how small are the errors and how good job LightSpace is doing using it's Anisometric Patch sequence and Drift Compensation feature enabled.
Anisometric sequences are better suited to displays that have any form of ABL, such as Plasmas and many OLEDs, where Sequential patch ordering can cause display overheating (overheating can actually be an issue on any display that has high peak luminance outputs, as it can cause the display to drift. Anisometric patch sequence is using an algorithm to display the patches with one dark/one bright patch order in simple words.
With Drift Compensation feature enabled and with 50 value, it takes a one White measurement per 50 patches and at the end it's including to the correction 3D LUT any display 'drifting over the time' issues, LG's are not stable displays over the time and this helps a lot to the final 3D LUT generation.
These details are for those who need to get the best possible picture for SDR from these OLEDs
