In that case there would be objective evidence of a change and you would be
conscious of this evidence. But if neither you nor anyone else noticed a
change, it wouldn’t matter. For example, if my colour qualia changed every
day, but there was no objective difference and I didn’t notice any
difference, it wouldn’t matter. It could be argued that such a change is
not really a change at all.
