It’s nice that Voyager has dark mode, but if I open it at night, in a dark room, the white splash screen blinds my eyes, even if it’s visible only for a short duration. Therefore, I’d like the splash screen to be a dark themed one, if dark mode is enabled.
I think this is more a thing with your device
So basically Voyager is just a website with a fancy shortcut in your app drawer. What’s happening is most likely in the few milliseconds before Voyager loads your device shows a blank web page which is white by default
That’s probably out of the dev’s control
With a PWA (assuming platform support ofc) the dev can set a screen to show while the app is loading, much like a native app
