I don't know shit about fuck, but you explanation seems correct.
I do remember hearing that precisely because of the limitations of vinyl compared to CD, music is mastered differently for each medium. So the CD master of a certain song might be more compressed (dynamic compression, not digital compression) to make it sound "louder", while the vinyl release has a wider dynamic range. So some people might prefer the vinyl version because it actually does sound different to the CD version.
Keep in mind tho, I might be spreading misinformation here.
