Emily is 175cm? source? according to wiki she is 170cm.
"The standard is 178 minimum", as you know this is not a rule. Lily Rose Depp, Kate Moss. Sara Sampaio, Halima Aden, Laetitia Casta, Hailey Bieber - all around 170cm. We can not rule out them as exceptions.
"At most she could have been a social media influencer." this is just your opinion just like mine Ruby having a supermodel type look.
Like I said Emily or lot of other supermodels look less glamorous than Ruby to me.
To be a supermodel, beauty and fitness are not the only things to consider. Some get enough grooming and opportunities while others do not. That deos not make them less beautiful,
