Is Dell U2410 considered "wide gamut"  monitor?

Yes, it has a wide gamut backlight and covers 96% AdobeRGB.

A bit of a tangent, but thought somebody here might know -- is there an industry standard for how these "percentage gamut covered" figures are stated?

I assume they put the gamut and the triangle formed by the monitor illuminants in the same colorspace, and say an increment in any direction is as good as any other, and calculate the fraction of the gamut's area covered by the monitor's triangle.

But which colorspace do they use? CIE xy with the 1931 2-degree standard observers? CIELAB? Something else?
