Too low contrast on standard swiftUI buttons in visionOS!

I have a fairly standard app for visionOS, created using SwiftUI. I have not added any customization, so I regard this "out of the box" graphics.

Legibility is far too low. I know I can change that, but by default, SwiftUI should generate UI elements that are within WCAG2 specs.

I changed my button to include a a buttonstyle, but it still looks the same? What I am doing wrong? Or what is wrong with visionOS?

Button("Immersive photo") {
 Task {
  await openImmersiveSpace(id:"ImmersiveSpacePhotoWrapper")
 }
}.buttonStyle(.borderedProminent)
