Yep, that's the conclusion I'm coming to. Asked DD what the story was as I sent two orders. What I got back was a zip file with two folders of pictures. The numbers on the folders don't match the order numbers, etc, no response from them. Assumed it was both chips. No clue what I'm really looking at now.
At this point, I'm no closer to an answer than I was back in Sept when I originally sent the samples in.
Broke down and ordered 98% sulfuric, test tubes, clamps holders, bla, bla, bla. Guess if I want real answers in a timely fashion, I'll have to do it myself.
Cost of all that crap, cost of another device to harvest samples from, another digikey order for more known good samples. My quest for a quick decap and compare is getting fairly costly.
