Alexandrian there are a good percentage of Ethiopians who don't speak a semetic language (they speak from the cushitic branch, which originates in Africa). You're referring to the Amhara who are a separate ethnic group of the many within Ethiopia.
Also Ethiopians, like other east africans typically have large foreheads (which arabs don't have) and small noses (which arabs/middle easterners don't have). And other anatomical features not really found in the middle east like large frontal teeth and long limb ratios. If they were hybrids they would look more closely middle eastern (bigger noses, sloped foreheads, bushy brows etc).
Bottom line east africa is diverse. Ethiopia is diverse. Semitic is only spoken by a minority of Ethiopians. Some Ethiopians are mixed, most probably are'nt. This goes for most of East Africa.
