while i can see the point of nothing can be gained by telling the wife but dont really think its true, you dont know what she thinks or what she is going through AT ALL, maybe she does suspect but he has talked his way out of it, maybe she has family pressure so she dosnt want to leave just because she feels like he might be cheating but they would support her if she had proof, telling her would give her that proof and if it were me it would hurt to know for sure but then i WOULD know for sure at least and that is what you can gain telling her, basically being honest to her when the person she should trust the most wont tell her the truth, that imo is worth the hurt
of course it could go the other way too and she may want to be in denial and doesn't want to know, will still believe him ect then really telling her wont harm her either because he will likely make up some crap that she will buy and it will be a blip in their week
the only reason i say dont bother is if the op doesnt feel like getting involved in the drama, then that is her right and i wouldnt blame her for that
