Maybe, maybe not. If there is miniaturisation of hairs at your vertex, thne yes you are. If there is no miniaturization then you're fine. I'm going to assume your doctor didn't check for miniaturisation, my advice is go see a hairloss/hair transplant specialist. GP's tend to be a bit clueless with regards to hairloss.

There is a lot of scalp visible though, it's strange, usually scalp is more visible with wet hair, but for you it's moreso with dry hair. It doesn't look bad by any means, but it's worth checking into.
