i wasnt too happy when i opened the brand new box a few days ago ,zoomed out the barrel, stuck a flashlight from the top and saw about 30 tiny particles of very light dust on the inner section of the lens. It was all on the circular ring part. Its not behind the outter part of the lens, but the part behind it. Basically you have to zoom out fully to see all of them, otherwise you dont notice it. Its also pretty hard to see them without a flashlight shining through the lens.

Not sure why it would be dusty already.  However, you did post elsewhere that the lens is performing well.  Exchanging it might just open you up to the risk of getting one with poor image quality (or other issues).

Videos online make it look like cleaning this lens behind the front element is way too easy.  Also, I have read that the front element on the 70-200mm f/4 is only $70 to replace.  If the 17-55mm front element is that affordable, I would forgo the lens filter/protector and just replace the element if it ever gets damaged.  Seeing as you would have mastered removal and replacement of the front element by then
