This is a noticeable problem with color mixing LED lights as well. If the exact wavelength of red is in line with the red receiver in the camera, then the camera interprets that red as a much stronger source than it appears to our eyes. It is commonly seen by anyone trying to take phone video of a rock concert, any blue light on the stage is completely blow out on the video. I imagine it is a similar thing with gemstones.
