no, chuck has always had ambivalence over Bruce. Chuck was a champion of non-contact, that's just where the sport was then, it looks pitiful today and it's nothing to really be super proud of. He has a ton of skills but in those days, if you chose to compete, you generally had to play the game that way.
Rumors were, they actually did spar and Chuck was left embarrassed, how true that is who knows but I was always always suspicious of a guy who seemed to get his hackles up every time Bruce was mentioned, even though Bruce helped his career. Story was that Chuck and the rest of the martial artists around were mainly scared of Bruce when he was alive. After he died? well..., Also, as I always mention, you don't get good perspective from anyone in the same line, that's just not how it works. Would Joe Frazier say a lot good about Muhammad? No, even though Muhammad beat him to a pulp the last time they fought, that's just how it works. Same in music and maybe even worse, the wannabes take shots at legends and claim they are better, if they are, they never made it work out for them.
