I'd be a bit surprised if they did that for RGB/VGA or any
HDMI that is using RGB encoding. The video decoding comes before the
RGB part, and the basic display tech. is RGB.
(ie. there is no way you'd want to encode RGB as video and
then decode it again.)

In an ideal world displays RGB displays are additive, but we are not
in an ideal world. If there is any crosstalk between the individual
channel value of a pixel, and if this crosstalk is non-linear or
if the pixels response to the control values are non-linear,
then the light output will not be perfectly additive.
