I have a Pioneer VSX-01. I did the auto calibration about 5 times when setting it up when it was brand new. Now the AVR has about 200 hours of use and just did the auto calibration again. Every time the channel decibel setting has been set about 1.5 lower on all channels. Nothing has changed in the room and speaker positions are all the same. Why would that be?

Is your room and receiver frozen in time? Things have changed, you aren't aware of them

the computer chip in the receiver is.

Maybe the transistors have become polarized at the quantum level

Hard to say what would cause such a difference. Seems unlikely the receiver has any issues.

Yes, about 2 minutes should do the trick. It's your brain that breaks in, not the amp. Are there measurable changes, yes, are they audible, no.

Yes, Pioneer amps need to be Broken-in. You should have purchased an Onkyo, they are pre-broken-in
