When you set each speaker to produce 75dB at your seating position we can predict the loudest signal normally recorded on a DVD or Blu-ray (which should be 00dBFS) will be produced at 105dB with your volume set to reference level. You can set this level manually with a SPL meter or an auto system setup routine like Audyssey will do the same.

Yes, that’s the way it works – use test tones in AVR to set SPL at listening position to “reference level” (typically AVRs use test tones at 75dB for this purpose) and then when you are watching a movie set the volume control to 0dB for reference level. It will be pretty loud – most people end up listening at -6 to -10dB in my experience.
Q. What are the reference levels in digital audio systems?

The professional standard reference is +4dBu, while the semi-pro reference is -10dBV, and, because these two figures use different reference points, there is just under 12dB of difference between the two.

But, depending on whether that recorder is consumer or professional, 0dB could be one of two actual signal levels. On consumer gear, it references a .775 volt signal while the professional level is referenced to 1 volt. Now, a quarter of a volt may not seem like much, but in the audio world, it’s pretty big – 14 decibels big.
What is "reference" level? - AVS Forum

Average reference level is about 85db with ideally 20db headroom for peaks on the main channels and 30db headroom on the LFE channel. 75db is the typical calibration level that most avr's put out, but is not considered reference listening level.

Assuming that the room correction software on your AVR set the levels correctly (all bets are off if you didn't run it) then 0db master volume is considered reference level (105db SPL). You're preference is -7.5db below reference. (Mine is -15db to -10db). You can get a simple SPL meter and enable the test tones in the AVR for each speaker.

Reference level is a calibrated volume setting used for both movie production (in dubbing stages and post production houses) and reproduction (in screening rooms and theaters). The human hearing system is non-linear, especially in the bass, so having a consistent... www.acousticfrontiers.com Save Reply Oleson M.D. Registered Joined Feb 3, 2010

Consumer Line Level (-10dBv) Consumer and semi-pro gear is typically -10dBv. This is the common output level for DVD/CD players and old-fashioned home tape recorders. Historically, these outputs are RCA connectors (commonly called phono plugs) or …
YouTube Changes Loudness Reference to -14 LUFS

This. Changes. Everything. Well, OK, not really. But something important did change last week: YouTube quietly changed their playback reference level to -14 LUFS.. Wait, WHAT?! Weren’t they already doing that?. No. YouTube has been using loudness normalization for years now, but until recently they weren’t using LUFS. In practise the results were likely to be …
