I'm always mildly surprised when people make such assertions about the domain of science because it is simply wrong. Blind testing of "perceptions" is how cognitive science progresses. Far from being unsuitable, it is ideal for truth determination of this kind.

Yes, that is true. Only systematic and well made tests brings knowledge forward in a reliable way. Belief, based upon reality, or not is always unreliable.

So, when a photographers says - I bought this fantastic camera and it has an impressive dynamic range - then you better ask - how do you know? And if he says - it handles high dynamic scenes excellent. Yeah - maybe he is right. Who knows?

But - tests do only measure what test do measure.

So - if someone says - I think far away parts of landscape images have a certain delicacy in rendition - then - how to measure that?

But you don't have to measure that to come up with a "who is better" or "who is Foveon" kind of test. Though that can certainly be worthy of study in its own right.

Check what tools psychology has for quantifying subjective assessments - they exist.  One common test for example to assess depression level state uses a set of questions and scores accordingly.  There are other questions that have "on a scale of 1 to 10" - and of course you have to adjust for other factors.  It's not trivial effort to do this right but not impossible- to at least get something useful.
