Only bootleg and labels that issue unofficial out of copyright vinyl use a CD to transfer.
No legit label uses a CD to master to vinyl. They use only a digital file, at whatever resolution the originating label sends. In 2022, it is unimaginable to think that any mastering studio has a CD player hooked up to their mastering console. They don't, the digital file resides in the mastering suite hard drive, and is mastered from there. As well, no one uses SACD as a source. Again, why bother? Outside the classical realm, SACD is a failed format, and even in that world, only survives as hybrid discs to supply the installed SACD base. You could perhaps use a DSD file, but doing so for vinyl would be fairly rare, as no one aside from some minor audiophile labels records to DSD. Sony in Japan still uses DSD for some vinyl mastering, but only high bit rate DSD which far exceeds the resolution of a SACD player.
DMM can be done from analog tape or from digital. It is still widely used - MOV and GZ and two examples. Actually, DMM was developed for vinyl production at the beginning of the digital era, and many of the first DMM titles were digital, from labels like BIS, Chados, Teldec and others.
