The ColorHug is a colorimeter designed to calibrate screens with an approximately-sRGB gamut. If you're trying to calibrate a wide-gamut screen with a ColorHug it isn't going to work very well. If you need to do anything other than consumer hardware you need to use a spectrophotometer (that can do spectral profiling) rather than a colorimter that's calibrated to different primaries than what it's trying to measure. A spectro is going to cost you at least $300, and a good one is going to cost you somewhat more.
