I've tested the profiles with a few shots of parrots. The second profile leads to information loss in the shadows (gray -> black) and thereby to some artificial local contrast enhancements. I think it's worse than the standard colour matrix. With the first one everything looks fine. Blue tones are not changed significantly compared to the standard profile (a bit lighter), red tones appear lighter, but also more red (the standard contains some pink hues). According to the colour picker in Geeqie the RGB values changed from (roughly) (180, 0, 30) to (190, 0, 20). Overall the .icc profile produces a more vivid image.
