in relation to shadow and sheen, this would make for undesired
complexity and
variation in the results.
I'm talking about the Standard Observer: 2-degree and 10-degree. Not
measurement geometry of spectrophotometers. Existing spectros support
both, it's just that for ICC stuff we're asking the device to report
data based on the 2-degree, not 10-degree Standard Observer. Why?
