Before you let the door hit you, please answer the question. How do you know you have a 105dB reference?

Yes, it has everything to do with it.

You set the SPL, 85dB or 75dB and the distance for the MLP.

The gain or volume for each channel is individually set to the calibration reference, 85dB...

Sorry, no not trying to win, trying to help you understand.

You need to check your math. A 3dB increase in SPL requires 2X the amplifier power not 10. This can be objectively measured.
Here's...

Maybe, but I would disagree. You calibrate to 85dB for THX.

I also qualified my answer by saying "Theatricality" and based on "nominal" impedance.

I don't think it is a particularly good idea either. But, it won't bring about...
