Your hair looks very similar to mine. When I started CG I thought my hair was a definite 3b, but as I've been going alone my curl has gotten looser and softer, and now I'm much more 3a. I think it's pretty common for your curl type to change while going CG, so I wouldn't worry.
FYI, "texture" is actually referring to the thickness of each strand--fine, medium, coarse, more so than the curl pattern. However, commonly in the straight-haired friendly fashion world "texture" means any curl/not straight hair. But for us, it's the properties of each strand.
