That reminds me of the 2011 contest in Düsseldorf, and its reveal of the green room, but with the screens opening the other way.

Indeed - this was first attempted in Riga, Latvia 2003. Obviously no fancy LED back then - they just rolled up the black cloth with star light effects on it to show them sat behind the stage. I remember being wowed as it had never been done before and was a complete surprise. I think that may have been the first time where the green room was actually in the auditorium itself and not in a room backstage. Weirdly, it wasn't done again until Dusseldorf 2011 but having the green room in the auditorium in some form has generally been a common feature for most years since (Malmo 2013 and Israel 2019 being the exception due to limited space).

I suppose it's a better compromise than last time it was held in Malmo Arena - having them in another conference room and then walking across the elevated walkway felt a bit awkward in 2013. A slight shame they can't quite get the atmosphere you get with the fans literally every side of you and the chance for them to interact as the show goes on. However, at least they'll see the audience faces and hear the atmosphere.
