One more thing, I don't use a navigation bar. I use gestures instead (swiping from bottom & sides), plus the gesture guide is hidden. It may be frustrating at first, but once getting used to it, you might be enjoying it.
Also, there is a hidden feature that the status, navigation bar, and always on display slightly shifts its position in few pixels apart.
Actually, the "hidden feature" is already activated by default but mostly unnoticeable on daily usage. Here's some screenshot compilation of the status bar slightly adjusted. You may check your saved screenshot and compare.
