I've been somewhat underwhelmed by the mixing on this as well, as I feel they could have done much more interesting things with the tracks that I hear are available.
The last few days I've been going over the song 'Lady Love' from my 7.1 base Atmos rip in Audacity; and this is what I'm hearing in a detailed breakdown.
I believe in Audacity channels 5 & 6 are Rears and 7 & 8 are sides IINM.
Let's start with the LFE:
- this is a somewhat reserved low end bass at around 40-120 hz and peaking at 60 hz.
Next the Center channel:
-nicely isolated Bass guitar here
("I actually like that use for Center, might have liked the vocals more in the Center also") with only a hint of vocals and a couple of guitar licks.
Now the Fronts:
- starts with Cowbell in both L&R (so centers it in Front-
"not crazy about that decision")
-a distorted rhythm guitar comes in, also some Drums and Vocals, and a little later some shaker mainly in the Front Left;
the Drums, low level bass, Vocals are all in the fronts.
-later on the guitar solo comes in at a couple of points, also mainly in the Fronts.
Next the sides (7&8-to stereo):
-has some muffled low level bass and vocals in it.
-mainly, it's some distorted rhythm guitar, which sounds like 2 different guitars one Left and the other Right (probably the same ones as in the Fronts, just more isolated. This can be heard clearly when there are the occasional slightly cleaner (perhaps just through guitar volume control) strums, i.e. at 30-40 sec.& 1:03-1:13.
Finally the Rears (5&6-to stereo):
-This is were it gets real interesting to me, with very isolated cleaner guitar tracks.
Left Rear (5) has clean guitar strums; and Rear Right (6) has some fairly clean guitar slide licks.

"would have liked these to have a little more amplitude in the overall mix")
Here's what the 7.1 wav file looks like in Audacity-

Here is what channels 5&6 look like once I raised them +8dbs so you can see them better-
