I suppose it is a bit like when I once wondered what Aurochs (wild bull, now extinct) tasted like. Someone pointed out that, even if one WERE able to bring them back from extinction, being farm raised would probably make them taste more or less the same as beef does now. In fact, probably the closest thing to the taste of actual aurochs now would be some of those feral cattle that exist in Australia (though even there, you'd have differences due to changes in genes and a differing diet due to the different flora) .
