I've probably come across more CD's than LP's that I would consider poor recordings due to the mastering process. Some due to the era of the Loudness Wars and some basically flat sounding.
What does bother me is when I purchase a remaster or reissue to replace an original LP from the 60's or 70's that had seen better days and while the new copy may not have the noise from wear the original copy sounds much more dynamic than the remaster.
