But you did say it was a sign of status by saying "yellow for a beta". This statement suggests that beta werewolves only have yellow eyes. I see now that this wasn't your intent.

That exactly what it means. If there's nothing to support your claim, then saying that Kate and Sebastien are mutations is unsupported speculation at best. No. They didn't become normal werewolves, however, they weren't referred to as abominations and mutations like Jackson was.
