Motown records would have been mastered on analogue reel to reel and the same masters would be used obviously for CD re-issues so whatever is on the CD will be on the vinyl in terms of frequency range. A Revox reel to reel Tape machine running at 15 or 30IPs for example can have a frequency range of upto 45khz.
Maybe what you are thinking of is the fact that Motown stuff is all mastered very loud, essentially compressed by overdriving the desk, which is something incidentally that you can't do today with digital desks, because it was mastered to sound louder on a jukebox than all the other records.
This is a legendary production style which still exists today in Detroit and is why producers from all over the world go to The National Sound Corporation.http://www.metrotimes.com/editorial/story.asp?id=1376
