It's funny your source is myths about vinyl...
So these sources are saying LP is 20KHZ. The best is your link on myths....which says "Commonly there is audio content up to 23-24 kHz on many vinyl records.". Again, I previously mentioned source content was up to 20khz...during the age of analog, there was no consistent >20khz reproduction.
Myths or not, these links support my assertion that vinyl can go beyond 20khz. One of links talks about the ability to successfully put 122khz (experimentally) on vinyl and the fact that quadraphonic had 50khz content which kind of blows the 20khz limit you had mentioned out of the water (not sure how they did it). I also wonder what direct to disk recording limits are also (going to look into that). Also I believe that newer audiophile recordings are not necessarily limited like the analog age recordings were. In any case this is a fascinating discussion that I consider valuable, although probably not changing hard held opinions. We have beat this horse pretty hard.
Edit: Here is another link that supports higher frequencies on vinyl and mentions that tape machines were flat to 20KHZ and rolled off at only 6 to 12 DB per octave. So there could be significant info at 40KHZ.
