Instead of the areas affected as looking flat, shelf like, reduced in sized, and the contour removed, then they would be on a hub doubled, doubled die raised, (not incuse as MD shows) enlarged, (not reduced in size like MD) showing a spread in the centers of the devices, (not affecting the edges of the coin with a shelf look) and showing contour of the devices, looking doubled of that design. (not a distorted view of an alteration of the devices, from machine movement) Here is more information:

On a strong DDR on a quarter you can see the spread on the centers of the devices:

The top image is a normal coin. The lower one is showing the enlarging of the devices, contour intact on all the devices. You can see the spread on the centers of the devices.
