Light mode: Dark sidebar on Windows but light sidebar on iOS

[ag14 1]

Why is it that the light mode sidebar on iOS is white, but it is black on Windows? On another discussion on the Dark Sidebar, a member of staff posted that the dark sidebar in light mode is a design decision. Why is there a discrepancy then? Many of us would prefer to have all light panels on light mode and all dark panels on dark mode, like in iOS.
