Exactly. If I haven't used an "animated" GIF, a side by side comparison would not have revealed the difference easily.
Does that not serve to ask the question " If you can't really notice it why buy it?"
It's not strange to see that one of DXO's test images is the architecture shot (of the columns) using a 15mm fish eye

sorry but who's not going to get barrel distortion with that combination??
Tried the demo/trial myself and TBH found that it did exactly what it said on the tin but:
The lens distortion correction never reared it head as I has taken predominantly landscapes or portrait shots where nearly all the information was in the centre of the viewfinder.
Lens softness wasn't a problem as I was (lucky enough) to be using a mixture of canon
'L' lenses with both a 20D and a 5D
Colour correction and or levels was not quite to my liking :shrug: so I ended up with the images in CS2 at the end of the day anyway.
I don't batch process all my images from a days shoot. Never have, always go through and pick the keepers. So the idea of this saving me processing time by setting it off running and watching it process three hundred images doesn't appeal to me.
All in all doesn't for me appear to do much more than what Rawshooter Premium can do.
But if your a photographer who takes a lot of architeture shots with poor fisheye lenses and needs to process every shot on your return to base then I reckon this will do the same as many other products on the market but a little bit quicker
As said earlier I thought the idea of being ripped off for a few dollar more just because I decided to by a better camera is a bit of a joke.
