Re: VT30 Gamma 10 point issues
Generally … the good reference calibration will be the THX mode one. The custom mode can then be used to create that Day mode version … much brighter. The 10 point grayscale does work in the custom mode … but since you are dealing with a day mode … try to start with the wide color triangle and only deal with the brightness of the colors … not the xy position. Room light shrinks the triangle anyway for the human eye.
