I rebuilt the profile using V1.1.0 RC1 and that orange spot is indeed gone. The lower left image had banding around the sun, it's gone too.
The gamut of that image is pretty wacky. There are lots of pixels with L* = 100 and a wide range of a* & b* values, so that the gamut volume looks like it's been cut with a knife at L* 100. Not very natural looking compared to a device gamut. Whether this is an artifact of sharpening in Lab space, or truncating over white values I'm not sure. Using a severe filter level (ie. -f50) with tiffgamut started to make the volume look a bit more reasonable though. With such a large gamut I wonder whether there is a danger of over compressing during gamut mapping, resulting in a "dull" looking result. cheers, Graeme Gill.
