I think from a sound quality standpoint, there could be no difference unless something is incorrectly done. Where you could see a difference is in the timing of the WAV files by a VERY small amount if you do not quantize your CD Track Splice Markers before doing any rendering.
For example, if the CD Track Splice Markers are not quantized in the montage before you render the DDP, they will be quantized when the DDP (or CD-R) is made. For most projects, this may not matter but for a live album or album with songs that overlap/crossfade with precise marker placements, the CD Track Markers could quantize to an undesirable place.
So my personal practice is to always quantize the markers before I render anything related to normal music/album projects, so I know where the markers will end up. This way, whether I render WAV files of each track from the montage, or WAV files are exported from the DDP Player or ripped from a physical CD, the tracks in theory will be more perfectly matched as far as timing.
To check for any sound quality changes and other things, you could do this null test:
Render a 16-bit WAV of a track from the montage
Export that same track from the DDP Player
Make a new 44.1k montage
Place the two WAV versions on their own montage track
Make sure they are lined up perfectly in sync (down to the sample level)
Insert the Stereo Tools plugin on one of the clips and invert the phase of both left/right channels
If all is done correctly, there should be only silence when you play the two files with one phase inverted.
