Graeme, I made a test by generating a cLUT profile only (-ax) in Argyll 1.5.1 and the problem is still there. I looks like the artifacts are not related to the matrix profile only, then!
Well, I'm not sure what you are seeing then. My testing indicated no noticeable differences between the XYZ cLUT created with V1.4.0 and V1.5.1. The only noticable difference was in the matrix values. Graeme Gill.
