Please advice

That appears to be factory. It looks a little darker than Sepia Brown.

Could be have been painted that way at the factory. But would likely be a special wishes color.

Look on the ledge, to the left of the engine cover latch for a silver paint-code sticker.

Looks too purple/red of a brown to be mocca

Outstanding job on the overlap. I can see what you are saying.

OP's car kinda looks like a fresh BC/CC respray whereas the Google search I posted looks like single stage urethane with hardener - more original-ish. Less bling shine but very nice depth.
