Having checked Qt source code, I don't believe it is intended behaviour:
enum { // Shell image list ids
   sHIL_EXTRALARGE = 0x2, // 48x48 or user-defined
   sHIL_JUMBO = 0x4 // 256x256 (Vista or later)
};

Also, when looking into the folder with Windows Explorer the Icons 
absolutely do have bigger sizes.
Should I create a QtBug report for this?

Best regards,

Sebastian
