From the pictures -- Looks like chemical stain-salt smog,etc. My granddughter last year ink pined my wifes BMW- very good leather. I being the smart guy put some laquer thinner on a rag and cleaned it off. The end result is just like what you have. Knowing that a BMW seat would cost almost as much as my Kirkham- I used all my power- what the hell! I first colored it in with shoes polish-my seats are tan- black should we way eaiser. Worked it in then started treateing/ cleaning with the white milky looking leather treatment- don't know what brand but it is what upholstry shops use. My wife can not tell where the problem is - I can though. BUt it turned out very nice. THe lamborghini club detailer uses model car paints to touch up spots in leather all the time. Good luck- I think with a little work you will be fine- looks like you are a driver as most of us so you can probably tolerate a little more than most Porch guys would.
