The total luminance gain relative to the nominal luminance gain as a function of the Contrast [7:0] setting is as follows:
Luminance Gain = (nominal_luminance_gain)
× [Contrast[7:0] / 64 / (2MC) + MC - 1]
Where MC is the contrast multiplier setting in the Brightness and Contrast Range Extender register at I
