The Pro isn't a flat out cropped Max; you can tell because the bottom edge looks like a proper die edge, and there are subtle places where the break line wouldn't be straight (compare the DDR channels with the rest of the blocks, they don't line up slightly). The Max is a cropped real Max because they tried to hide the die-to-die interconnect (meant for a 2-die Max machine) at the bottom. You can tell because the die abruptly stops at that edge hard, without the expected features of an IC edge. Clearly if they'd gone as far as photoshopping that on for the Pro, they wouldn't have screwed it up on the Max ;-) I'm not aware of any other public die shots of the Pro, but there is one of the Max that went around on Twitter and it matches the marketing shot, plus an extra strip on the bottom edge as we'd suspected. We do know the M1 Pro has a completely different and smaller package, however, and the M1 Max die would not fit on it. That one was leaked months before the announcement as part of the board layout and schematics for that machine. So the Max die simply wouldn't fit on Pro machines, and this is from engineering drawings.
