I'm not arguing against for or against that fact. I'm arguing that these "testing" methodologies are flawed. I'm, apparently, doing a very poor job of expressing the distinction.

Let me state in as clearly as I can:

* A good test would ensure that the luminance values for all colors matched exactly throughout the test image.

* Said test would need to be displayed using a device that is calibrated to ensure displayed luminance matches encoded luminance.

* A test that pulls color data from a source image with mixed luminance values in each channel is flawed.

* This statement makes absolutely no claim as to the human ability perceive any of these colors.
