Better question, do we need them? Maybe someone with better eyesight than me would spot something, but I really cannot tell the difference between a 4k monitor and a 1080. Likewise with a refresh rate that is twice what my current monitors use. I mean, if someone wants that sure, why not, but wouldn't that extra power be better spent to eke out more battery life? Because I wasn't annoyed with how things look on my monitors for...at least 15 years. What I AM annoyed with however, constantly, is how quickly batterys go flat.
