I just rescanned a chart I printed made with Canson Photographique Matte 33 years ago. It was formatted to match a ColorChecker but in the standard 33x29 patch size so it could be read on an i1isis. Each ColorChecker patch is a set of 9, 6mm squares with a 6mm border and was printed using Abs. Col. to set the RGB values.
The Ave deltaE2000 across the 24 CC patches was .27, Worst case was .44. How much of that is instrument drift and how much is color change is not known. But all in all I'm pretty surprised at the color stability.

Insignificant, invisible and yes, part of this is instrument noise of which, we have no idea without lots of testing on your part (which I'd suggest, is a waste of good time used elsewhere, maybe taking photos;D).
