I think that is true of most Presidents, and congresscritters, too, for that matter. We usually don't find out what really happened with most POTUS' until well after they leave office. Some of this is due to personality, some of it is just politics and some of it is because there are certain things that you just can't talk about when you wield that sort of power and influence.
