Yes, there are two 'issues' here.
One as you point out are two sets of color numbers that are the same color (my
sRGB example). So two color numbers that are separated by extremely small
increments that are indistinguishable from each other, in my example, by a mere
deltaE of 0.01 are indeed ONE color. And no, they are not invisible, if they
were, they couldn't be called colors.
The other 'issue' are numbers that are not at all colors as they cannot be seen
(my ProPhoto RGB example).
