"color rendering capacity" is not documented in any color vision or colorimetric text known to me. search results show three hits for the term: this wiki page, the original 1983 paper by xu he, and a web page whose neologisms suggest a chinese author.
the main problem is that color space is not a volume; its dimensions are incommensurate and its space is not euclidean; for example, the chromaticity area implied by hue differences is roughly twice the area implied by chroma differences. there is no standard way to "count the colors" within a chromaticity plane, and illuminance, not illuminant (assuming the light is broadband), is the main source of colorfulness and lightness contrast in surface colors (the phrase "one unit luminous flux" is incoherent jargon, and if the intended meaning is one lumen then the color measurement is being done by candlelight). finally, "color rendering capacity" is simply another term for "gamut", already widely established as the limits of a color space rather than its volume, and algorithms to compare gamuts are in wide use and have many practical applications.
rather than merge, i propose that the "color rendering capacity" page be deleted, as i suspect it is self promotional. no other wiki pages link to it.
