AFAIK there's no way to programmatically detect when an ImmersiveSpaceContent is dismissed by a user (i.e. by pressing the home button). By comparison, ImmersiveView has .onAppear() and .onDisappear():

ImmersiveSpace(id: appModel.immersiveSpaceID) {
            ImmersiveView()
                .environment(appModel)
                .onAppear {
                    appModel.immersiveSpaceState = .open
                }
                .onDisappear {
                    appModel.immersiveSpaceState = .closed
                }
        }

In comparison:

// No similar callbacks for here:
struct MyImmersiveSpace: ImmersiveSpaceContent {
    var body: CompositorLayer {  /* ... */  }
}

Hi there, I actually found a way to do this via the layerRenderer state!

For reference:

func renderLoop() async throws {
        // Render loop.
        while true {
            if self._layerRenderer.state == .invalidated {
               // background.
            } else if self._layerRenderer.state == .paused {
                // inactive
            } else {
                // active
            }
        }
    }
