Yes, and let's get rid of this "looks a *BIT* different" stuff.  Let's just
keep things simple so we don't get distracted with things that don't
matter.  The pixel either has a redness quality, ,or a greenness quality.
If it is a fact that the quality of the knowledge changes, or if the
quality doesn't change, over space and time, the person both must be aware
of those facts, and they must be able to report those facts of the matter.
In other words, the quality of the person's experience of that pixel is
dependent on it's particular colourness facts, consistently over space and
time, and they will know if they do or don't change, over space and time.
