Plus the fact that a TOS-style Gorn skeleton (in fact a pretty close match for the TOS look) was in Lorca's private lab aboard Discovery in Season 1 of that series. The Kurtzman Era has given us TOS-style Gorn specimens in both DSC and LD and these more xenomorph-like ones in SNW. Could be that both looks are Gorn but just different genomes and "Gorn" could mean every sentient spacefaring species within the Hegemony and not just one species.
