On iPad / iPadOS 26 (using light system) the wordmark changes from light to dark based on the wallpaper color after a slight delay.

On iPhone / iOS 18 (running dark OS) the same does not happen and the color does not update with menu or tray open/close, what triggered it was pulling control center:

What can be seen here is the Apple status bar clock also struggling to adapt to a visible color … and the label "Shortcuts" changing color to invisible at that point.
