Facetime HD camera blurry? (early 2011 iMac)

Question

Using Photobooth and iChat, I'm comparing the camera in my new early-2011 iMac (27" i7) with the camera on my older, late-2007 model iMac. The newer camera simply looks ... blurry to me. Both if I'm up-close or sitting far back from the camera. Hard to tell objectively if it's "broken" or not, or if the new camera is just un-satisfyingly "softer". Anyone noticing the same thing on theirs? i won't keep these up forever, for but now here is the "same" pic (computer in the same location, anyway) from the old and new iMac. Notice more details in the older pics, in the hair, cat bed, eyes, etc.
Old iMac first :
And now the new iMac :

Anyhow, I took the new iMac into the Apple Store today and set it up side-by-side with an equivalent computer. There was a detectable difference, my iMac wouldn't get as sharp a picture as the store's computer. The exposure balance (?) on the store's computer was also superior (my camera had extra-dark blacks or was easily over-exposed). The Apple Store guy said he hadn't seen this problem before. They can't easily repair the cameras because I guess they're so integrated with the LCD display, he said the only logical thing to do on a new computer is return it and order a new one.
While waiting for my Apple Store appointment I tried out a number of the floor computers with the new Facetime HD camera. Even when comparing comparable computers (same lighting set up / facing the same direction in the store) some of the cameras were noticeably better than others. I didn't wipe off the store cameras, so maybe there was public smudging going on ( ! ), but a couple machines has a really nice, crisp picture and great colours. Most of the others looked fine. A few were, to my eye, "below average". One (a 2011 Macbook Pro) seemed almost as bad as mine.
