I have compared waveforms and frequency profiles of ripped DSD vs DVDA vs BluRay vs lossy versions of the same mix and mastering. In all cases *where these are the same* the only potentially substantial difference (i.e., in the audible range) I've seen was the LFE. LFE content for multichannel is all over the map generally (some mixers barely use it, some use it only for the lowest bass, some put full range content in it) but between different formats of the same mix/mastering, the difference comes from the bandwidth limit conventions for the LFE channel of lossy formas (AC3 and DTS) -- typically their LFE contents are lowpassed at 120 Hz..
However, the common (often selectable) LFE lowpass setting in most AVRs is either 80 hz or 120 hz anyway, so the audible difference would be minimal.
NB too that how an AVR is 'supposed' to treat LFE varies from format to format, regarding whether or not to account for a 10dB level offset..
Needless to say none of this has conceivably much to do with the flowery claims for one format for the other made by their proponents. The main channels aren't different in the audible range--- unless the mastering has been obviously altered..
