You can see a visual representation of the two mixes in the jpeg above. The upper wav files are from the Rhino version which was a bonus track on the "Brain Salad Surgery" DVD-A, one of the very first DVD-A's released back in 2000. The lower wav files are from the Steven Wilson 5.1 mix from the new Sony release. I know you cannot tell much by looking at these pictures, but you can see right away that there is no brick walling, loudness war crap, or over processing.
The Rhino doesn't look overly processed in the amplitude domain to me either, from the looks of it, unless you consider the overall level difference to be too much. (FWIW, higher magnification of the front L/R reveals there is no brickwalling in either channel -- just some mild peak limiting , mostly in the front left channel)
Here's a brief run down on the 5.1 mix comparison.
First off, center channel on the Rhino version is strictly the bass guitar! Very strange, as if you do not have a big center speaker, you are in trouble with the lows!
No more trouble than if the bass was played from 'small' L/R. Fortunately for most systems regardless of where the bass is mixed, the lows will be routed to the sub....which it should be, for speakers that aren't full-range.
But if you have a center speaker that is grossly mismatched or frequency restricted compared to the other loudspeakers, and/or isn't crossed over correctly to the sub, then there will be issues.
Btw from the graphs, it appears the Wilson mix of this track simply doesn't use the sub as much as the Rhino mix, perhaps explaining the reports of 'no low bass' . (I hear sub output in my setup, though-- it just doenst vary much in this track). What's odd that the Rhino left surround and right surround channels are so different in level throughout the track, with the left surround channel being notably louder than the right (they're very similar to each other throughout Wilson's mix) . I don't recall hearing then when I listen to the track, but I'll have to recheck. [UPDATE: It appears to be because there are drums in the LS channel, but no drums in the RS channel-- RS also much more devoted to acoustic rhythm guitar)
From about 3:00 on we can discern interesting difference in mix choices for the Moog synth section of the song, between the Rhino and Wilson's.
