Please understand that the way screens display colours and brightness differs from device to device. I edit on a calibrated monitor, and try my utmost to maintain consistency however tactile printed media may differ slightly in appearance to what you see on screen. It is the nature of the transfer from a backlit display to paper that reflects light. Even the colour temperature of the environmental ambient light may marginally change how an image appears. It is not a significant change but I would rather my patrons understand the science behind it.
