I've read that an early CD issue of the Callas-de Sabata Tosca was a bit fast and sharp. And the same company, EMI, issued a CD of the Klemperer's recording of the Mahler 2nd a bit fast and sharp, hoping no one would notice, because at the time CDs were limited to 80 minutes, and the performance is 80:15. So they sped it up slightly. Maybe at the time they were afraid of going over 79. (They first issued it on two CDs, and then on one, speeded up.) So it has happened, but like you I was under the impression (perhaps incorrect) that the problems with turntables generally being slightly off was pretty much not a problem with CDs.
