I think there is a very visual component to that as well. I am, let's say, mildly obsessed with detached soundscapes. The Tidal Contrivas seemed to fit that bill, even more so after having been equipped with Harmonix RF-999MT feet. Now, the Contrivas are large, surely they look elegant and are as slim as they can justifiably be (i.e. not a pencil-style speaker), but they are visually prominent.
So, as Tvad put it somewhere further upstream, was I getting the last 4%? After I gave up on surround some time ago, I had hooked up the TV in stereo mode, and there came my confirmation. The visual center was now, unavoidably, the screen. Sonically, things were happening in the entire room but even if I tried very hard, from where I was sitting I could not identify the large black sculptures that happened to be in the room as well as their source. For anyone with a large screen between the speakers, this may be the acid test.
