Tube matching question

At the risk of this sounding like a dumb question I am going to ask anyway. I am new to tubes, so be gentle. I just received a quad of matched KT88's for my integrated. While so far they sound awesome there is one little thing that bothers me and I know its truly cosmetic, but one of the Gold lion labels is all messed up. It wouldn't make such a big deal but they face forward and you see these 3 beautiful looking gold lions and the one all messed up. When I asked the place about it they said thats the luck of the draw. I know cosmetics means nothing sound of course. My question is if I were to purchase another pair, how much would that mess up the matching if I were to replace 1 or 2 and then keep the others as a backup? Does that all sound dumb and I should just be happy they sound great?
Thanks

A key point about tube amps here.  If your amp does not have individual bias settings per tube, they must be a matched pair at least.  Ideally, all tubes should be matched in a channel, but pairs that share a bias setting must be closely matched.  Not all matching is created equal, but that's another can of worms.

I tried the GL KT77. There is only a label on 1 side. They are near 10 years old, so maybe the labeling in now like the KT88.

Enjoy the PL regardless. It sounds pretty good with any tube.
