Just because something looks the same to our eyes doesn't mean they are the same colour. It does matter, as our eyes and camera sensors will have a different response. They are supposed to match each other, but it is more complicated than that. Side note: the human eye can see near IR! You can build a cheap filter using several layers of primary red and congo blue lighting gels and see for yourself.
If you have tried intentionally photographing in IR or UV, you will know how much (or not) sensitivity there is. So I'm not saying it will never be noticeable, but in practical circumstances it will be swamped by visible light and likely be insignificant.
So for now I remain to be convinced that is a mechanism at play. I have proposed a method by which it could be tested, but do not have the time or resources to carry it out any time soon.
