I wasn‘t aware there was any ‘official’ game that requires calling more than just the pocket (?). The missed ‘4-rail-around-the-table’ shot that drops in the pocket I was aiming at shouldn’t spark any controversy in 14.1. Disgust (my opponent) maybe. Glee (me) for sure!

Yes, it is always sufficient to just call ball and pocket and any way the ball gets in is fine. (Bank pool is the obvious exception. And bar rules are not even remotely in the discussion.) The problem occurs when the ball doesn't go "cleanly" like the 4-railer break shot. Depending on how the "call shot" rules are written concerning "non-obvious" shots, the shot could technically be disallowed.
By some rule sets, if you are playing an obvious combination it must be called. Under the WSR the requirement is that the referee must be satisfied that the intended shot was made. Under CSI rules we have:
When playing call shot games, remember that shots defined as not obvious, and safeties, must be explicitly called. There are no exceptions under any circumstances, regardless of how simple or obvious the shot may appear. ...
4. You must always call shots that are defined as not obvious. This rule applies regardless of whether or not your opponent asks about the shot, and regardless of how simple or obvious the shot may appear.
I think this means that if you can either cut a ball into the pocket or shoot straight at the ball and make it in the pocket by kissing off a nearby ball, and you say nothing and play the kiss shot, the shot is disallowed under CSI rules.
Also under CSI rules, if the 7 is sitting right in the middle of the pocket, and you roll the 6 onto the 7 to make the 7, you better have explicitly called the 7. The ref is not allowed to judge intent in that case.
