I could not care less about any refresh rate over 30.

You can care about it, but that just means it sounds like a differentiator to me, not something everyone should pay for just because you care about it.

You will have to somehow prove it if you would say that the panel and driver chip are all already ready to do 100+ hz for free by default, and are actually artificially limited, and that that artificial limitation doesn't come with some other advantage like battery life (allowing a smaller battery or less cost in some other way).
