There is nothing wrong with the bike. If you look at carbon layups with clear coats, you can see something like this on pretty much every piece ever molded.
Carbon fiber itself is very fine and silky. It's laid up in multiple plies and set in epoxy. Picture many layers of loose, very fine silky threads frozen in clear glue. Sometimes there will be a little ripple, or one sheet of carbon fiber will end, and you can see that.
Some manufacturers are better at layups than others. Some put a cosmetic weave coat over the top. But what you see here is very normal and no cause for concern.
I agree - the beautiful smooth and seamless weave you frequently see on frames etc is usually a cosmetic layer and doesn’t reflect the multilayered structural- and frequently less aesthetic nature of the layup underneath. The carbon sheets are layered for function and strength, not beauty, and these sheets have to overlap somewhere. If the manufacturer chooses not to cover the whole thing with as seamless-as-possible top layer , the structural nuts and bolts of the layup will be evident - like here
