Does this appear to be vertex balding?

For a while now I've been constantly taking photos to check on the changes my hair might be making. A little while ago I made a post of a strange line formation happening in the center of my scalp that I was curious about. I've taken pictures under my bathroom lighting and noticed how thin the vertex has suddenly become. I know this is under lightning but surely hair that wasn't thinning wouldn't look like this?

What do you guys think? I'd be really grateful for any feedback.
Again, I understand there are so, so many people out there that are way worse off than I am. I simply wish to nip it in the bud as soon as I can before it gets worse off for me in the long run.
God I wish everyone's hair problems would just go away.
