I understand that, but most if not all of the flights long haul I've been on have had that same system. It was simply that the AF flights listed had that symbol whilst the others didn't and I don't know of a long haul that doesn't have the same pop up/fold out screens rather than ceiling screens in J or F. In fact I can't remember the last time I flew with a ceiling screen.
I do remember a while ago that BA gave F pax a DVD player to use on their flights as their screens and systems were so out dated. Wondered if AF were doing the same sort of thing.
