It's subtle, but it is the difference between Cinema adding 10dB of LFE and Discrete removing 10dB of LFE.

You have to remember that the LFE setting on the processor is not referring to the physical subwoofer but rather the LFE source data stream.

So, my expectations of the bass management system would be:

CINEMA mode:
LFE: +0dB
Any channels mixed into LFE: -10dB

DISCRETE mode:
LFE: -10dB
Any channels mixed into LFE: -10dB

ie any channel mixed into the LFE stream always get -10dB because the physical subs will be playing 10dB louder than the main channel speakers and thus the offset is needed to keep the mixed bass at the correct volume.
