On Android, @expo/ui/community/datetime-picker with presentation="dialog" renders the Jetpack Compose DatePickerDialog, but the only color customization it exposes is accentColor (mapped to color). The underlying DatePickerDialog already supports elementColors (DatePickerElementColors, including containerColor), but the community wrapper doesn't pass it through.
The dialog also always creates its own Host, so wrapping it in a Host with seedColor has no effect. As a result, the dialog background falls back to the Material 3 default / dynamic color (e.g. light purple), which can't be matched to the app theme without dropping down to @expo/ui/jetpack-compose's DatePickerDialog directly.
Request: add an Android-only elementColors prop (or at least containerColor) to the community DateTimePicker, forwarded to DatePickerDialog, or let it reuse an outer Host's seedColor.
