Stop trolling me Obee! You're missing the point. There is a diminishing return above 144hz yes but to suggest there is a maximum refresh rate at which there is no perceptible difference is irrelevant because we haven't reached that point yet. Difference between 144 and 240 is proven fact but you won't see it on a youtube video on your 60hz or 144hz monitor for obvious reason. If your reaction times suck to begin with then it won't help you but if you're a serious competitive player then it's gonna help. The bottleneck is yourself or your wallet.
