Why are all generated splash screens for iOS on the same size?

On iOS the @1, @2 and @3 images are all 2732x2732 px.
Xcode also gives a warning when running "The launch screen exceeds the memory limit and may not display during app launch. Use images requiring less space."
Shouldn't these be smaller for @1 and @2?

When the app is launched, you first see a black screen. If I reduce the @3 to 2400x2400px I see the splashscreen instead of the black screen again on an iPhone 14. I have to do the same on an iPhone 6 with @2 and so on. It seems to me that the tool still has a bug here when creating the splashscreens.

Note: The changes are only visible when you delete the app and restart and reset the device / simulator.
