I think we're looking at more a case of the 'non-released frames'. Although they have yet to release anything but the L7 image, that is exactly what was colorized (its the left frame shown, as their color version matches 2P135241352EFF2702P2544L7M1.JPG). So, either the image is based on ...and this is an odd combo...L567 for rgb, as the produced image is called x_pubeng_Sol100A_P2544_*L567*-A102R1.jpg (*'s added by me) and they just haven't released the L5 and L6 images, for whatever reason, or its the left frame L7 and color info from the Right channel infrared spectrum (which would be odd on very many levels...)
