IMO, it's a myth, but I'd like to get some fedback from the experts......

Nope. I guess you are talking about top of piston-this is only one place where exhaust gases meeting the piston. We are talking in reasonable limits. Build up on top of piston makes difference, finish on walls makes big difference, but not in relation with exhaust gases
