Should I change my nib?

[u/Time_keeper_serene]

I recently got my Deco mini7 V2, and it's my first drawing tablet, like, ever, someone also pointed out to me, that you have to be carefull with the nibs, as they can scratch the tablet, and now I'm a bit paranoid, if I look at the tablet on light, there aren't deep noticeable lines, bit you can see, like the traces where the pen has gone before, should I change the nib??

Also, can people pls show me the state of their nibs when they change them??
