moving the RGB points at each IRE in the minus direction
lowers the luminance so gamma goes up.
increasing the RGB increase luminance so gamma goes down.
this is the general way.
use 2 point first. same deal.
then switch to 10 point and measure first to see if the 2 point changes stayed.
if the 2 point changes did stay, then you can use both 2 and 10 to bend the luminance curve to your target.
be aware, color temp D65/6504k will be done at the SAME time.
so first, run measures with different tv settings of both color temp and gamma settings to find the combo that gets the grayscale and gamma close.
