Hello Tano22,
We see you're having some issues with the status bar, and the colors of screenshots being inverted. We'd be happy to help out there.
We would first recommend updating to today's new iOS version, which is iOS 15.0.2: Update your iPhone, iPad, or iPod touch
What seems to happen to the font color in the status bar? Does it switch to a particular color each time? Does the color issue seem to happen when launching a particular app or feature?
We noted you turned off one of the invert accessibility features, be sure to check for any else that may be on in Settings > Accessibility > Display & Text Size, including Color Filters.
It may also help to try restarting the device when odd issues come up: Restart your iPhone
Take care.
