Assuming the image is not rotated or flipped 180 degrees, the more offending spots in your example are on the opposite side of the image (left side) of those who claim a lubricant spray issue (right side).
And as far as I know, everyone who claims this issue experienced the spots within a few months of use, and the spots reappear within a few weeks after cleaning and they always appear on the right side.
As an example, I just did the second wet cleaning of my sensor on 12/23/2011 and when I checked on 1/17/2011 there where 10 major spots back on the right side. But as my examples earlier in this thread show, the rest of the sensor from about 1/3rd in from the right side all the way to the left side is virtually free of debris.
But if you truly believe your camera is one of the possibly affected cameras, I would calmly and assertively argue your position.
As an aside, didn't you have to approve the repair before the could proceed? Just trying to be clear on their procedure because the correspondence I received seems to indicate I have to approve repair and provide payment information if its not covered under warranty.
