Then there's the fun of does your incandescent light match that of SIGMA's calibrated illuminant?

Absolutely not, young man!

It's a strip of five warm white LEDs bearing only the vaguest of resemblance to anything incandescent. I normalize my tests to eaxh other by color-balancing patch #22 in the editor and usually (not this time) adjusting it's L* close to the card value of 50.8 - all the while realizing that the spectral radiance of the said LEDs will cause some error in the results.

Not unlike the variation of the spectrum in daylight outside while the camera can only do "Sunlight" ...

Pedantry is hard work, but someone's gotta do it ...
