Here, I copied the IMG link and posted it to get the picture to show on the thread. That's how you get pictures into the thread.
There's definetly visible marks. If you drag something like a toothpick along the bore and over the marks does it catch against the marks? If it doesn't then it's not an issue. If it does catch on the marks then something should be done. You mentioned warranty so I'm guessing that it's a new gun. If it's an older one but new to YOU then you might be limited to other options.
One option I'd be tempted to use is a fire lapping kit. It involves using fine grinding compounds that you press into a few soft cast lead bullets then shoot down the bore. Once you shoot a few from medium to fine grit bullets the bores and rifling are supposed to take on a nice shiney look. And from the looks of your picture above this woudn't be a bad thing at all. The scratches or scuffs you noticed are the worst but the rest of the bore seems to have a lot of tooling marks as well. To me this appears to be a gun which would be likely to lead up due to the marks catching and shaving lead.
