I wouldn't use how Luffy's fruit as an example at of how other zoan works, even mythical ones. We assume zoan awakening is a whole new form, but it may simply be total control of it. Like Kaido buff mode, fire dragon, weird body between hybrid and animal he showed at some point could be the product of zoan awakening.
Yes Luffy did get a new form, but his zoan also has no hybrid or full beast form.

Either Kaido is stated to have it or not, this proves why we need these statements.
