Did something change with audio analysis?

I have used DCP-o-matic to convert dozens of .mkv files ripped from Blu-rays over the years. Anytime in the past I've analyzed the audio from one of these files, I never had a the True Peak line be red to warn me the audio was too loud.
But, today I'm trying to demonstrate to a local filmmaker where his audio levels should be in a film he's working on. The film is in 5.1. I'm using DCP-o-matic to analyze the audio from several different .mkv files ripped from Blu-rays to give him a visual example of what professionally mastered levels look like before his next test screening and they're all showing the true peak as being a lot higher than I thought they would be - true peaks louder than -3dB. I've looked at the audio from Blu-ray rips of The Lighthouse, Coco, Groundhog Day, Labyrinth, and a couple others to make sure I had good variation in genre. But after analysis, the true peak is always louder than -3dB. I don't remember it being this way using previous versions of DCP-o-matic.
Does that seem right? Maybe I'm just misremembering, but I could've sworn that most of the center track would hang out around -10dB for most of the feature.
I'm using program version 2.14.23. 2018 15" MacBook Pro - 2.4GHz i7 6-core processor.
Thanks for any help!
