I've studied this for my entire adult life.

My conclusions are that:

1.  We can measure things that we cannot hear.
2.  Some of the things we can measure matter more than others.

So I can reach a few conclusions from this:

1.  If I cannot measure a difference, then I certainly cannot hear a difference.
2.  If I can measure a difference, then I may or may not be able to hear a difference.
3.  To tell how audible a measurable difference makes, one can employ subjective blind listening tests.  That will help determine what is audible, and by how much.
I strongly agree with your point 3 that a properly controlled blind test will go a long way in bridging the gap between perception and measurement.

Non blinded tests are often biased as a result of expectations arsing from visual cues, prices of equipments and even equipment brand choices

I am not saying that blind tests are the ultimate method here, but it is a far better option than the visual testing method.
