The data is the data. Improving the reading of the data doesn't change the data itself, it just makes it easier to read.
Let's say that the data on a CD is not music. Let's say it's a .doc file. If this disc has a thumb print on it that causes readback errors that error correction can fix, you are not going to open a different document. You're gong to get the document - the only document. It will say whatever was written in it when it was saved to that file. It will not change that document to say something completely different.
CD music playback is simply a way to open a file. Unlike a file like a .doc file, these files are opened sequentially. That is the only difference between CD playback and opening a file. A document file gets opened and buffered until the whole file is read. CD "files" (music files) open as they're read.
Let me ask you to try this instead. Take one of your messed up CDs and rip a track to a .WAV file. Then, clean it up. After, rip that same track to .WAV file again. Play those two ,WAV files and hear for yourself.
