I don't know if this is still true, but I know that in the 2000s the vinyls usually were mastered better than the CDs. There even was a website comparing CD vs vinyl releases, where the person hosting it was lamenting this fact because objectively CDs have a much higher dynamic range than vinyls, although I can't find it now. CDs were a victim of the loudness war[0].

Allegedly, for a lot of music that is old enough the best version to get (if you have the kind of hifi system that can make use of it) is an early 80s CD release, because it sits in a sweet spot of predating the loudness war where producers actually using the dynamic range of the CD.

The loudness wars were mostly an artifact of the 90s-2010s, because consumers were listening on horrible plasticky iPod earbuds or cheap Logitech speakers and the music had to sound good on those.

Once better monitors became more commonplace, mastering became dynamic again.

This is most clear with Metallica's Death Magnetic, which is a brickwalled monstrosity on the 2008 release but was fixed on the 2015 release[0]. And you can see this all over, where albums from the 90s had a 2000s "10-year anniversary" remaster that is heavily compressed, but then a 2010s or 2020s remaster that is dynamic again.
