Is the wear of these tires normal?

I had these Continental 4 seasons tires installed in May of 2022 and have put roughly 1,200 miles on them since then. The bike is stored strictly indoors.

I was wondering if this wear is normal and if the bike is still safe to ride or if it’s time to replace. I also wonder if bike tires and their installation typically come with any sort of warranty.

I’m a relatively new biker and don’t have a good frame of reference for these sorts of things. I appreciate any guidance!
