Here are some SDR 150 nit Custom picture mode calibration results for the A9G. From my observations, it calibrated pretty much like the A9F, nothing significantly different. The Gray scale and CMS are very accurate and some of the CMS anomalies can't be corrected with user controls so it would be really nice if some day we could create a new 3D LUT like we can do for the LG to correct and or minimize some of these errors. I didn't have to make any "large" adjustments in the Gray scale or CMS calibration and I used de ITP as the deltaE formula. I find using de ITP gives the most accurate results if you have a meter that will read the lower IREs accurately and quickly. When looking at content that i'm familiar with, the A9G produced an excellent picture. It's hard to say if it's any better than the A9F because I wasn't able to view them side by side but based on memory the PQ is very similar.
You also have to remember this Sony comes from the factory calibrated to the modified JUDD white point and my guess is the 3D LUT "was created" with this white point as well since if you calibrate the A9G or any Master Series Sony with the JUDD WP, you tend to get more accurate CMS scans. These scans are for D65 calibration. The HDR scans were "normal" as well following the EOTF curve perfectly with a Peak Luminance of 700 nits with this particular set. I couldn't validate Dolby Vision because we don't have a test pattern generator which will trigger the Sony but DV content looked correct compared to the LG playing the same content near by.
