Description
When using Appearance.setColorScheme on app start, the change doesnt trigger a re-render in ios. I used the latest react native bare app and added a Appeareance.setColorScheme('white') in app component.
This works on android, thus the app will start in white mode. But it doesnt work on ios, the app starts in system mode nevertheless.
But the colorScheme is set to white, because if i want to set it to white again to trigger re-render manually, nothing happens, because i want to change it to the same value it is set to.
