Liquid Glass clear variant isn't clear

I've been experimenting with Liquid Glass quite a bit and watched all the WWDC videos. I'm trying to create a glassy segmented picker, like the one used in Camera:

however, it seems that no matter what I do there's no way to recreate a truly clear (passthrough) bubble that just warps the light underneath around the edges. Both Glass.regular and Glass.clear seem to add a blur that can not be evaded, which is counter to what clear ought to mean.

Here are my results:

I've used SwiftUI for my experiment but I went through the UIKit APIs and there doesn't seem to be anything that suggests full transparency.

Here is my test SwiftUI code:

struct GlassPicker: View {
    @State private var selected: Int?
    
    var body: some View {
        ScrollView([.horizontal], showsIndicators: false) {
            HStack(spacing: 0) {
                ForEach(0..<20) { i in
                    Text("Row \(i)")
                        .id(i)
                        .padding()
                }
            }
            .scrollTargetLayout()
        }
        .contentMargins(.horizontal, 161)
        .scrollTargetBehavior(.viewAligned)
        .scrollPosition(id: $selected, anchor: .center)
        .background(.foreground.opacity(0.2))
        .clipShape(.capsule)
        .overlay {
            DefaultGlassEffectShape()
                .fill(.clear)    // Removes a semi-transparent foreground fill
                .frame(width: 110, height: 50)
                .glassEffect(.clear)
        }
    }
}

Is there any way to achieve the above result or does Apple not trust us devs with more granular control over these liquid glass elements?
