Most paintings like that didn't have "glory" like that, Can. Nothing too blatant, at least - most anything they wear would be "generic" for the era.

With monarchs of England/GB since Elizabeth I, for instance, only two of their portraits on wikipedia have something that could be an indication - and one of those is an emblem for an order, so it is easily explained. Best as I can tell, similar specs for earlier than that and in other countries.
