From a cursory review it does indeed seem such displays (RGBW) are not
as good as pure RGB in terms of colour reproduction. They may be a bit
better in brightness. They are cheaper to make.
This does not seem like a machine a photographer w/should use. OTOH, if
you go look at one in appropriate lighting conditions and find it
acceptable, then that may be sufficient for you.
