So I guess I'm out of luck, and a manual greyscale/gamma with hcfr is the best I can do.
Hi, I always getting superior post-calibration results using eeColor 3D LUT Box with LightSpace CMS software to my Pioneer KURO LX-6090H.
I have used LightSpace Software for 3D LUT correction generation using 21-Point Cube size (9.261 color point measurements) with and CalMAN at the end only for verification
, not because LightSpace don't have verification reports, but I wanted to crosscheck the final results with other software solution also.
With Drift Compensation feature enabled and with 20 value for example, LightSpace takes a one White measurement per 20 patches and at the end it's including to the correction 3D LUT any display 'drifting over the time' issues, Plasma's/OLED's/Projectors are not stable devices over the time and this helps a lot to the final 3D LUT correction table generation.
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.
So LightSpace's engine received the data from all measured colorpoints and exported a 65-Point cube correction table for eeColor 3D LUT Box.
From that display characterization measurement data, I have generate 6 different 3D LUT correction tables with different gamma's (2.2 / 2.25 / 2.30 / 2.35 / 2.4 / BT.1886) for REC.709...each 3D LUT correction table with different gamma setting took about 2-3 seconds to be generated with LightSpace.
Below are some post-veficiation results using LightSpace for 3D LUT correction generation and CalMAN only
for verification report.

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.
