I never take claims that licensed adaptations of TV shows or films to another medium (comics, novels, whatever) are canonical seriously, whether or not there’s ever another filmed production to contradict them — which they almost always do, because the people who make the shows and movies probably don’t even read the adaptations, much less feel beholden to them. As far as I’m concerned, calling such ancillary material canon is just marketing. (Which is not to say it can’t be entertaining, of course.)
For example, AFAIC, there is no actual “Smallville Season 11.” The only follow-up to the TV series that counts in my book is the filmed coda provided by the Arrowverse’s “Crisis on Infinite Earths.”
