In his review of the Sony A95L, Paolo Centofanti wrote:
“Usually, the software calibrates on the native panel range of 2.2, while with a special LUT invisible to the user, the TV adapts the parameters for other gamma values and the different curves of the various HDR modes. The problem we have encountered is that this does not happen, and once calibration is done in this way, at a value of the “range” parameter of the menu equal to -2 the native range of 2.2 is set. On the other Sony models, the value -2 corresponds to a range of 2.4 usually. But since the minimum value is -3, it is not possible at the moment to get a range of 2.4 in this way. The solution is to proceed with the good old manual calibration.”
However, in David Abrams’ tutorial, he sets the gamma to -2 and the TV appears to accurately track the 2.4 gamma. Maybe we’re not understanding Centofanti’s explanation correctly. In any case, DDay.it’s calibration results for SDR were similar to those obtained in the Calman tutorial, with what appears to be a little over-saturation in the red, green, blue and magenta at the edge of the gamut.
Concerning adjusting the over-saturated edge colors, David Abrams says,
“If you’d like to tweak this a little bit more manually you can come up to the DDC controls, choose the gamut adjustments, and adjust the Hue, Saturation and Luminance for each color. These are the adjustments provided to us. As such, remember that these controls are going to adjust the red in its entirety, so you may find that while you bring in that 100% saturation you’re then desaturating the colors inside the gamut which may affect flesh tones. It’s often better to target more accuracy around the range of flesh tones and neutral colors versus targeting the edge of the gamut since those are going to be colors that aren’t used as much in content.”
Note: Sony issued a firmware update for the A95L series just days after DDay.it’s review, though the details make no mention of changes to the gamma adjustment.

You could use flesh tones but which skin color would be your calibration center point? The 2020 gamut is an xy table of values that contains all the possible flesh tones and temperature white points within its boundaries, but few displays can hit all the RGB primary endpoints. In a manual calibration, adjusting the color matrix RGBCMY will position your supported triangle of colors inside the 2020 space, and if you decide to pin it to a skin tone, or pin it to one or more of the primary endpoints of which the red and blue it can probably hit, or somewhere else in the middle is your calibration decision. Of equal or more importance is that the colors track the gamma curve, to your dE target.
Saturation and hue on the other hand can be set with patches of primary colors R,G,B overlayed by smaller flashing squares of the compliments C,M,Y, thusly a flashing square inside the patch. When you enable a R, G, or B filter, the compliment square becomes the same color as the primary patch but of a different shade. Adjust the hue and saturation controls until the flashing square disappears inside the patch, becoming the same color and shade. Do that for all three primary colors. That’s how I set my hue and saturation.
