No, it appears as if it was just altered in the ways that would help their case, in this instance. With the tablet filing, the aspect ratio appears to be altered - and perhaps not coincidentally, altering the aspect ratio in that filing was more beneficial.

The end result appears to be, in both the tablet and phone filings, that the alleged image manipulation produced something that appeared more similar to Apple's products. That the image manipulation is different (aspect ratio adjustment, vs resizing) seems to be more damning than if the same adjustment was made across the board (i.e. it looks less likely to be accidental).
