I don't think most novelisers were, really! The only bonus you sometimes get is if they've swallowed what passed for the show's bible, but most of the time they don't seem to care and you can't even tell if any other info is a flight of fantasy or actual info.
(The Public Eye one didn't even know Mrs Mortimer's real first name, and the Frontier one kept insisting that James Maxwell's character was so despicable he was Very Short (as despicable people are, I suppose, along with having my particular shade of blue eyes - so, really trust nothing I say!), so they clearly didn't look too hard at the cast list either, let alone anything else. The Enemy at the Door one was disturbing, but at least supplied some character info that I think must be genuine show background, because it fitted too well into what was said on screen but not elaborated on not to be.)
