Is this a scratch or dust?

Having trouble identifying exactly what this is.  Sensor cleaning (wet and blower) aren't working, but based on the way it "changes color" in the light now I think it almost looks like the emulsion on the sensor has rubbed off in that spot. Or is it just dust that won't go away?  Anyone else ever experience this?
