Do people with hollow cheeks have larger masseters or is it like 80% bones?

Hey everyone, recently I’ve decided to start jawmaxxing and part of that is just growing my masseters for dymo and while I was in the gym one day I bit down on something in the locker room and noticed a slight shadow on my jaw which surprised me

Even when I was super duper lean (skinny and mid) I never had hollow cheeks even though I have high set cheekbones with a bit of anterior projection too which really bummed me out ngl but I just accepted it that I can’t until recently

Looking at normally I *should* have some type of hollowing under my cheeks when I compare my face to others w similar or worse structure but then I looked and I saw that they probably have wider massters than me, my jaw is kinda narrow but nothing obscene which is what I wanna ask, has anyone who grew their masseters noticed a greater shadow after doing it?

I had hollow cheeks at like 15% bodyfat. Pretty sure it’s just bone structure + fat distribution.
