I’m pretty sure 11.1 broke this, but I haven’t been in ICC in a few months. When first entering the Upper Spire in ICC on retail, all of the pedestals on the central platform facing each wing already have their colored orbs present as though the wing had been cleared. Alongside this, the beam tether underneath each walkway which connected the wing to the central spire until the wing was cleared is nowhere to be found. This was on 25-player Heroic, though I have little reason to believe Normal would be any different.
I still don’t understand how this old content gets its visuals broken by patches that are 8 expansions newer. Antorus took over a year to fix the world soul’s animation behind Aggramar from BFA to SL, hoping this is a simpler fix. Details like this still provide flavor to the old raids, especially to people who may never have seen it before.
