AFAIK no sport has rules that differ dependent on the level of players.
I can think of some exceptions, but not many: tennis plays 5 sets in professional grand slams only, cycling specifies different lengths of time trial for different levels, athletics allows women in mass races to run with the men at most levels but not at olympic level, things like that.

Usually at clubs over here all kinds of infractions are made without the director being called. A change of call or play by the declarer is hardly ever a problem, some even ‘solve’ a revoke by changing the played card a few tricks back without anybody protesting.

These are the kind of players who consider calling a director as more or less an accusation of cheating.
But this is the fault of bridge as a whole. It's far too easy to put the blame on the players and say things cannot be changed. There are mediocre people playing every other sport too, but they still know the rules, expect to pay a price if they break them, and don't feel they are accused of cheating if the opponent points out to the referee that the ball was out or whatever.
