WindowInsetsControllerCompat.isAppearanceLightNavigationBars has no effect on navigation icon colors for SDK 35+.

Code:

// Go E2E to test behavior on SDK 34 and below.
// Don't use enableEdgeToEdge to rule out styles applied in enabledEdgeToEdge
// Shows setAppearanceLightNavigationBars has no effect on SDK 35.
window.setDecorFitsSystemWindows(false)
window.isNavigationBarContrastEnforced = false
window.navigationBarColor = Color.TRANSPARENT

WindowCompat.getInsetsController(window, window.decorView).apply {
    isAppearanceLightStatusBars = false
    isAppearanceLightNavigationBars = false
}

Navigation bar icon colors are light on SDK 34 but dark on SDK 35 after calling isAppearanceLightNavigationBars = false when the device is in light theme. Expectation is for icon colors to be light on all supported versions. However, icon colors do change colors if the device is in dark theme. With edge-to-edge, the app might need to have control over icon colors independent of the device theme.
