That's because in vinyl land they are trying to

The slew rate (speed) of the cutting lathe's tool head,
and the limits of the playback stylus' ability to read a
given peak. What is the window of operation that Vinyl
enjoys?
If memory serves, vinyl's dynamic range starts falling
pretty rapidly above about 8 KHz.
While CD-4 recordings were made with 30+ KHz carriers on
them, those signals were cut at very low levels. Playing
them tends to erase them after a few playings, even with
the best cartridges and stylii. People I know who have
experimented with CD4 tell me that about 10 playings is
it.
I wonder what format the audio tracks on a Laser Disc
were put down as.
If memory serves:
On older LDs, the sound was recorded in FM and also received DBX noise
reduction or something like it.
Later LDs had regular Linear PCM tracks like CDs.
