That's true, but it can also affect color accuracy for highly saturated
colors too - if any part of spectrum should be at a low level, then this
problem will tend to elevate the reading, causing errors in the a* and
(particularly) b* values. But errors in highly saturated colors are harder
to see, so perhaps this is not so significant.
