I lived in Louisiana for one basketball season and I worked a Salmen vs. Slidell boys game (2 whistle) that ended 93-87. I think I was still trying to catch up a few hours later
I think Chris Duhon (now at Duke) was on that Salmen team. He would've been a freshman or sophomore that season.
I think both of those schools are 5A. Slidell's fairly big, least it seemed so when I lived there.
To answer your question, I think it is obvious that teams at that level get a differently called game. Faster game, played more above the rim, and it takes a bit more contact to cause a disadvantage. The players and teams are more athletic and we adapt to the way they play the game.
Having worked some of the athletic schools in New Orleans for a season, it gave me an appreciation for big city basketball that you only get in a few places. Rut can probably address this question as well, coming from Chicago.
