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
