Even the world doesn't grant Luffy his 1vs1 win against Kaido because there were many factors which included Luffy's victory against Kaido. Sure, Luffy lost many times but that was against the same opponent who had to fight against top supernovas, scabbards and Yamato as well, without break. Meanwhile, Luffy got to eat something, recovered quickly and still took heavily damage from fighting Hybrid Kaido.
Luffy was at his absolute limit even before CP0 boss interrupted them. Kaido later demonstrated a much stronger Thunderbagua against Nika Luffy than the one which killed Bound Man Luffy.
Only G5 Luffy is comparable to Kaido but considering the fact that G5 is awakening and thus drains stamina faster than normal DF abilities, Luffy would still gas out faster than Kaido at the end.
Ultimately, as you said, Kaido didn't even show his awakening although it wouldn't wonder me if Oda confirms later that Blazing Bagua was Kaido's awakening or his buffed hybrid version. Yep, it would be shitty but it's not unlikely.
