Image to the entire screen of phone

Hi everyone,
Below you will see my splashscreen. What I ask is how can I stretch the image to the upper most part of the phone. I want it to stretch out including the clock battery part etc. Is this possible?

Hard to tell after the recent theme update. However, just play a bit with Page layout and/or legacy theme $paddingPageVertical. We have padding everywhere set to 0 and then add padding at the container where the image is stored.
