I don't think they could legally void your warranty if you did brake the tape and check the oil level, but more than 99% were too timid to pull the dip stick.A few of the smarter customers went home, drained the oil, measured the volume, and poured it back in. That's how it was widely proved that GM knew they had oil burners and were over filling. I believe it was mostly the 4.8L, 5.3L, and the 8.1L.
Interesting, never heard of that one.
Recently Hyundai and Kia gave owners a new dipstick to get the surface of the oil closer to the crankshaft.

If it was bad they offered short block or highly devalued buyback. This one is for the same issue but wont know till approval and such till may. Mine seems to be ok except it doesnt seem to hold 6th gear lockup on hills like it used to...

Again, as long as there is not foaming, no bubbles forming, it's fine to have some extra oil. For the OP's engine, 1 more quart out of 6 quarts likely is not a problem. Easy to check for bubbles too.
