Balding or just a whorl?

Hello gents, hope you are all well.

I’ve recently seen a couple of images of myself from above on a work CCTV system. I was confused as I had what looked like the beginning of a bald spot even though my hair is fairly thick and I don’t seem to have thinned at all on the front.

Its hard to tell from taking pictures as I just assume the worst, what do you guys make of the below picture? Just a whorl or start of balding on the crown?

Thanks in advance!
