Wrong laptop delivered, should I keep it?

I ordered a 2021 MacBook Pro 16” MacBook M1 Max 10c/32g 32gb 512gb from back market for $1.5k. I haven’t ordered from backmarket before so I thought I would give it a shot. I received a BNIB sealed 2021 MacBook Pro 16 with a M1 Max but it has the 24core gpu instead of the 32. I know I don’t need the 32 core gpu but when I saw it at that price I thought it was a why not deal. I was shocked to see a new unit come, I was expecting something used and possibly scratched with the wrong power cord and a few hundred cycles on the battery.

Now I’m torn, should I keep it since it’s a brand new unit and I know everything is new or do I try to return it and gamble again on what unit they will send me in return? My 2013 MacBook Pro broke so this is my new replacement so this would already be a big jump for me.
