The PA system is used to announce to the cabin non-trivial details: emergency exits, how the safety features of the airplane work, what is expected of passengers during the flight, flight times, expected turbulence, late arrivals, etc. These are not "mundane" details.

As well as stuff like how much drinks cost, what you might see out the left side of the plane, where to find a catalog of ridiculous items you would never buy, etc.

90% wasn't related to non-trivial details. I was there, ahduhl. Credit card offers, menu options, etc.

The safety talk was at the beginning of the flight and it was much lower in volume than what I'm talking about.

My guess is that the attendant's mouth was too close to the mic and they were just talking way too loud.

It's mundane when everyone is keenly aware of the details.

You cannot assume everyone does. You certainly did not when it was your first time on a plane.

Also if you get on a new model plane, things might be different.

I thought the point of the high volume was to get thru to the people who were ignoring it because they already know the message.

The point isn't to not do the presentation, the point is to acknowledge that most people ignoring it don't need it and hence there isn't a need to YELL IT SO LOUD OVER THE PA THAT EVERYONE IS AT RISK OF HEARING DAMAGE.
