good stuff.
last year Sonys would only have an accurate gamma in Cinema mode?
This years Sonys require Custom mode.
Becareful when doing 10 or 20 point white balance because point 7 (as an example) may affect 50-80 %.
As a general rule of thumb always measure 20 points even if the display only has 10 points of adjustment. Also always do an entire run of measurement after doing each point to ensure no interaction.
