New app installation on iPhone 13 on rare occasions loads with 2x resolution

Very rarely (has only occurred twice thus far on a few hundred installations) on iPhone 13 device with iOS 15.0, the launcher image and screen resolution has loaded in with the 2x image despite having higher resolution launcher images available. I have not replicated on any other devices. These are always clean installs from appCenter after deleting the previous version. What could be causing this issue?
