Have I got something wrong here.
I thought the new setting display.usedesktopimages should work both for IOS and Android.
But it only works on my iPad.
I tried withe a 4 level multi tiles + mobile and tablet images.
This made the iPad load the 1024 level
<display usedesktopimages="true" devices="android|ipad" />
My android phone loads the tablet images.
