they described a few episodes on one of our satellite broadcasts in the early 2000's, but it's never been comprehensively described on any official release, physical or digital, to my knowledge.

The majority of mainstream, Hollywood blockbuster-type movies after 1990 will have been described twice and probably more (we have four versions of Goodfellas, I believe there are at least three Sixth Senses, Snowpearsers, and Brokeback Mountains, in Northamerica, Uncut Gems was immediately described twice, by Dianne Newman for Netflix and Nicol Zanzarella for the theatrical/DVD track), while independent, unconventional, lower-budget, and foreign films are less accessible to us (though this has just begun to change, as studios like IFC Films and A24 have made an active commitment to describing every new release.) If you look at Martin Scorsese for example, all his mafia/crime movies are described, and we've even got After Hours as a treat, but Taxi Driver, The Last Temptation of Christ, Kundun, The King of Comedy, and Bringing out The Dead are not (except in geographically-restricted TV broadcasts), does that distinction make sense? It's the same with classics that were described retroactively, we have no problem watching Alfred Hitchcock, the Godfather Trilogy, or Night of the Living Dead, but David Cronenberg's early body horror films, Elaine May, Paul Schrader, and Hal Ashby get left behind.

ETA: in case that explanation was totally incomprehensible, you could also just look at the listings on the ACB's $1 to get an idea of the current selection (keep in mind, however, that it is US-centric by design and does not account for AD programming in England, Scotland, Australia etc.)
