It can be argued that if chess is a forced draw from opening position, then first move advantage doesn’t exist at all. Yet even if someone showed proof that chess is drawn game, humans would still atribute some advantage to white. Its not completely unreasonable that someone migth derive advantage from playing with more familiar setup (assuming one would play this variant enough). Quantifying this advantage and comparing it to first move advantage is another story though.
