If it is a ruling that could be detrimental to SMU, you never show it. If detrimental to the opposition I would certain like to see it but there may be a show them all or show them never rule.
I recall a game a few years ago that a replay was shown on a questionable call and the opposing coaches saw it and called time out to give time for review. Jones went ballistic and rightly so.
Of course after the review is announced and underway I would think it could be shown.
