Looking at the seat, I had a BMW that had the same issue. An upholstery specialist can dye this and set it so that it doesn't bleed. It is not expensive, so I would be shocked if Tesla didn't fix it for you. It looks like my CPO had some seat work done, after I conditioned the leather I noticed it was done very well but when you have your nose right on it, you can tell a slight difference.. Or it could just be leathers natural tendency to hold colors differently. I would not be discouraged at all by that one issue. Congrats on the new car it is beautiful.
