<<To Moose's observation of the eye seeing an entirely different color

Agree totally. Sometimes the sensor just can NOT reproduce what is
seen--divergence from "Luther-Ives" conditions.
Whether a sensor can accurately reproduce colors in a scene is indeed
independent of the converter but difficult to measure and quantify.
The SMI (Sensitivity Metamerism Index as defined in ISO 17321--recertified in
2017) tries to provide some quantification but is not sufficiently
discriminatory.

This uses only one standard illuminant and an 18 color standardized color
patches. The sensor accuracies will differ with other illuminants and other
non tested colors. In general those sensors with thicker CFA will score
better, but there are outliers and small differences are not significant.
Some may wish to know for example, that one sensor is more accurate depicting
greens with daylight illuminate or facial tones under illuminate X. SMI also
does not address the IR issues and depicting true purple--not turning it pinky.
It is clear to me the optics Ph.D.'s at DXO working with photogs can vastly
improve upon useful color accuracy metrics.
Off color, Mike
