Discovery season 2 also showed the original (not even TOS remastered) Enterprise design in previously on footage of The Cage, though the shot of the Enterprise did not come from The Cage. Lower Decks, Picard Season 2 and Prodigy have all had the TOS Connie design show up. Though the appearance in Picard S2 is barely visible. Only clear shot is from BTS images. Both designs are still valid. Both exist in canon. View it like a recasting. The Enterprise is now played by a different actor, but it is still the same ship.
