Drop an ICC profile on the left. This page reads the header at the offsets ISO 15076-1:2010 gives, names the colour space the profile describes, recovers the primaries behind its stored colorants, and runs a conformance check in which every finding cites the clause it enforces.
What it will and will not tell you
It reads a file. Whether the display or press the profile describes still behaves the way the profile says is a question about hardware and an instrument, and no amount of parsing answers it — a profile that is internally perfect can describe a monitor that drifted two years ago. That limit is in the Data register as an absence rather than left implied.

Three terms, each reported on its own, because a single blended score hides which one decided the answer. The white column reads “matched” for every row by construction. The readout this replaces added a raw white-point distance, and every conformant profile carries a D50 white against reference spaces defined at D65 — a fixed 0.08853 penalty on a scale where “High confidence” needed under 0.02.

Area is reported in the CIE 1976 UCS. The last card is the 1931 xy figure the bar chart used, kept because it is what the industry quotes — measured across the reference spaces it overstates Adobe RGB by 18.2 points and Rec. 2020 by 16.8, and understates ProPhoto by 14.4. And an area ratio is not coverage, which is what “136% sRGB” reads as; both are printed, each with its name.

What counts as a defect
A conformance check earns its severity from a clause. Two of the rules on the page being replaced could not.
