I assume the dissapointment would be equal if you see a character on the cover while on the comic store.

As for this case, yes, it doesn't warrant a page, but there's nothing preventing us from mentioning the character on the appearance list (without hyperlink) under "Other Characters", tagging it with the "Cover Only" template and also giving a note explaining the circumstances.
