Do all remastered vocals in vinyl albums have been 'corrected" with auto tune?

Hello.

A few months ago, I switched to  vinyl albums from CD`s and streaming. After listening to quite a few remastered records, seems to me , IMHO, that a vast majority of  the vocals have been modified/enhanced with auto tune and pitch correction. There does not seem to be a false note, at all, even in live recordings.

Hence my question: are there albums that have been remastered , and vocals not altered in any form, so the authenticity of the artist music has been reproduced?

If so, where would I find these?

I listen to classic rock, classic music, opera and blues.

Thank you for reading.
