I recently swabbed my K7 sensor to remove two stuborn specks of dirt. I had to do it 3 times before one of the specks was gone, the other one remains. However where the one dark speck was, there is now an artifact that looks the same size but instead of being darker than the background, it is slightly brighter. I am attaching two images (both magnified). I'll bet when the speck of whatever it was dislodged, it took some of the sensor coating with it! Sombody please tell me I'm wrong. So, I guess I will have to send it back to Pentax for cleaning, repair or waranty voiding. If the sensor is damaged, can it be repaired or replaced or have I spent $1000 for a camera that is now damaged 3 weeks after I purchassed it. Any info or advice is appreciated.

P.S.; To be clear, the top image is of the frame with the speck still on the sensor. The bottom image is after it was removed, but note what remains where the speck was. What is that? I used American Recorder swabs and Ultrapure TO.
