The stereo 2009 CD box set just sounds odd to me, a little bit unfamiliar if you like. I'd go as far as to say it sounds like remix. The effect is almost subliminal, and won't be apparent if you have not heard the vinyl recordings.
For me the bigger gulf is between the analogue and digital versions rather than the stereo and mono ones.
