Differential Axle seal - Opinion - replace?

[vidkidruss]

Hi,
I'm new to the forum and have found all the how-to's and advice very valuable and helpful for working on my son's 2000 SE.
So today I was working on replacing the passenger side cv shaft and even though I was trying to be careful in removing the inner joint from the differential, I seem to have "creased" the seal slightly. See picture.

So do I need to worry about this and replace the seal? If I do, any write up or instructions on replacement? I'm hoping that this is not bad enough to replace.
Thanks very much for any help!

IMO, if you're already right there, I'd swap it just to be safe. Although it doesn't really look that bad.
