It was DI'd, but it was created at the beginnings of DI. What I tried to express is that the excesses of a new format/technique/… don't instantly follow its introduction, there's a lag until a herd decides that's something to do. Same as the loudness wars: the Red Book was published in 1982 but excessive compressions started in earnest in the early-to-mid 90s blossoming into low single-digit dBFS by the end of the 90s-early 00s.
