Cool research. Looking forward to the details. Thanks for sharing your results so far.

Regarding "blacked out" do you mean just the normal solder mask? If so, there's nothing nefarious with that, it's SOP for modern PCBs as it keeps solder to the pads and helps prevent bridging and corrosion.

Also, I wouldn't be surprised if, given the density of the circuit there, this is a 4 layer board. They'd want to avoid that to say cheap, but there's a lot going on on that board.
