Ok so the discrepancy between Rtings and my Color Volume measurements is, by default the Sony's have Peak Luminance set to Medium even in HDR which "increases" the CV. I calibrated the Sony with PL set to High to get the maximum brightness in HDR. Please note the Peak Luminance control on the Sony works slightly differently than on the 2019 LG and the blend of the white sub pixel with the RGB sub pixels is different. On the Sony with PL set to Off you can only get about 100 nits of brightness and as you raise it you get more brightness to the max in SDR or HDR. On the LG you get full brightness with PL set to Off and small increments, I believe 40-50 nits more with each increment, as you raise it from Low to High in SDR. In HDR it's always set to High.
That said, I re-measured the CIELab Color Volume on the A9G with PL set to Medium and High in HDR then the same with ICtCp color space like Rtings. I also included the C9 Color Volume that D-Nice took on the C9 with PL set to High in HDR. I also included the Rtings page with their A9F color volume measurements for comparison.
The A9G I worked on today at VE where I took the measurements the Peak Luminance in HDR, D65 measured 700 nits. These Sony's can go higher with smaller windows but as we discovered, they manage the peak HDR brightness differently than LG.
