Well, yes, there may be difference.
When you calibrate, you need to do it with a known signal input level before setting the master volume.
A receiver's test tone is at -30 dBFS(full scale). So, when you set your master volume unless the receiver does that automatically, the volume
you set each channel to is 75 dB SPL.
-30 was selected for homes because of loudness while level balancing the channels.
Theaters use -20 dBFS and 85 dBSPL as it is much more dampened and a larger volume so 85 dB may not be that bad.
So, if you just run up the volume to get 75 dB, it may not be the correct known level.
