They knew, you got not a new logic board, but a kind of emergency repaired one. To me it looks like your board had been major stripped from bad chips and then balled it back with new chips. The repair tech used a bit too much of the glue. Thats not a bad thing, however it shows you, that you did not get a new replacement logic board from the factory one, but a reballed one.

So, a little bit of a secret about Apple repairs... at a certain point, they don't use new parts because there are no new parts left. Every repair will use refurbished parts from that point on.

They don't have a giant pile of brand new Macbook Pro motherboards lying around, especially if this is a Radeongate machine. New motherboard stock was probably depleted long ago.

Every motherboard replacement this guy gets will be a refurbished board. It might look different, but it won't be a new board. Apple is likely all out of new boards, and they won't be making more.

IIRC, the terms the AppleCare agreement let them use refurbished parts at their discretion, but I've never actually looked for that term in the contract.

(Same applies for iPhones btw. If you have to swap, unless the model just launched, you will not be getting a brand new device in return. It'll be refurbished.)
