Hi Rob,
This is the reply from one of our engineer that you may
found useful:
------------------------------------------------------
If "screen shot" uses XReadScreen(), then the pixels will be
read back directly from the framebuffer without gamma correction
applied. Gamma correction is not applied during video refresh
until after the framebuffer contents have been read.
The default gamma correction value is 2.22. Try:
fbconfig -dev ifb0 -G 1.0
or
fbconfig -dev ifb0 -G 1.6
to see which value is closer to the PC.
