Who cares how dirty the filter is? The filter is designed to remove crap from the oil. If its getting dirty, its doing its job. The larger question is what condition the oil itself is in after 15k. Its a bit too soon to say definitively for this particular car, but anaysis by Blackstone labs of the N54 in other cars has shown that 15k on a full synthetic is perfectly fine.
