Certainly there are a lot of stories about it taking more than one trip. It's unfortunate, but I would say the path of least resistance is let them try again.
But the indoor/outdoor issue is interesting. I'm not an optics guy, but the little I know makes that sound really odd. Even though clearly a different wavelength, it's not THAT different. How much brighter/dimmer was it though? Is it possible the focus is simply inconsistent, and these were what you happened to get. If you do them again might they both be different? Or maybe it was dark enough indoor it was inconsistent there?
When I sent mine in, it took them DAYS to "look at the images". When I got it back it was much better, was symmetric left to right, but still off between outer and center focus. But not so much as to be a problem. So I'm satisfied, if not impressed, by their service now (NY by the way).
