Top bar in full screen mode is different color than dashboard background in full screen

**Home Assistant Android app version(s):** 2025.8.7-full

**Android version(s):** 16

**Device model(s):** Pixel 9 Pro XL

**Home Assistant version:** 2025.11.1

**Last working Home Assistant release (if known):** n/a

**Description of problem, include YAML if issue is related to notifications:**

There is a bar at the top when in full screen mode. it is not the same color as the background so it's a bit jarring. I get that there is the camera hole, so not sure if it needs to be accessible for actual elements (though it would be nice so I can work around it). Attached is a screenshot. It is my understanding that in light mode the bar is white, which again would be jarring.

**Additional information:** Ideally at the very least the bar at the top would be the same color as the background color for the dashboard you are on.
