Shadorne,
I just played my Bluray for the first time and I concur with your assessment. The CD is most notable -IMHO- for what it lacks: compression. It appears to have been recorded at a significantly lower level than most of this ilk, and - for me - must be cranked to appreciate. It also offers a nice sense of space and air around the performers.
The Bluray sounds quite similar, but adds a more obvious dynamic quality, evident at lower SPLs. Still not demo quality to my ear, but awfully, awfully good for what is essentially a "bar band" style recording.
