Alrighty. When I got my DeVille, it had Good Years on the rear and crappy Grand-Am tires on the front. They were both white walls. When I got it, they were obviously never cleaned. So when I scrubbed them and used the Bleach-White on them they were good as new. The stripes were very white. I then got some new dunlops upfront. They're white walls too. At first, the blue stuff was impossible to get off. After that, the white walls are now sorta tinted tan-ish. right after you scrub them they're fine...but after they dry they turn tan. Even after I spray on my tire shine, they're still tan. My dad suggested to use a wire brush on them...but when I tried, it felt as if I'd rip the coloring off completely...so I never bothered.

Re: cleaning dunlops??
I got two words for you: Brill O. Brillo is one of the best tire cleaners around. The steel wool is very fine, and will not leave scratches. But all of the dirt will go away.
Major tip. Do not, I repeat, do not, use the same bucket of wash water, that was used with the Brillo, to finish washing your car. The soap in the Brillo, will stain your paint. I had this happen many years ago, on a black pick up truck.
I did that after the scrub brush. Like, I sprayed on Bleach-White a few times then scrubbed. It got the blue shit off. but there was this tan-ish tint instead of a white. After I scrubbed them again it was white for a few minutes then it went back...
Hmmm...kind of a shot in the dark here, but what about a buffer? And by that I mean the buffer pads or whatever you want to call them that you can get that will go on a drill. I know it doesn't sound ideal, but maybe it's worth a shot. Paired with a good cleaning substance (And you will want to try everythign you can think of) it may work. Maybe you should try something like PB Blaster or Sea Foam. One of those "rust eater" products. Once again, all just kind of random thoughts...things I would try if I had your problem. Hope you get it solved!
Have you considered that Dunlop might be using a tanish white rubber for their whitewalls? If you have all 4 of the same tires, you won't notice it. But if you have 2 different brands, it will show up.
And no amount of scrubbing will make any difference. To check that, take a pair of cutters or a sharp knife and take a thin piece of the whitewall rubber off the tire. Just a bit. Not enough to cause damage. If the rubber is still tan, then you are SOL.
If the rubber is whiter under the top layer, then you should be able to get it whiter by scrubbing it.
I have Dunlop SP40s on my Town Car and they get nice and white with Bleach white and Brillo. They do get less white within 7 days which I'm told is caused by the oils in the rubber penetrating through. Firestones and Goodyears seem to stay white longer; Michelins shorter.
