Don't rule the cable out until you've tried a different cable
1. Using the provided cable that came with the Xbox
2. The manual as is found here and the monitor itself says optimal resolution '3840x2160@30' in the menu when connected.
I've tried every single type of picture mode once connected and tried using both HDMI ports.

sounds like a faulty cable to me

Looking at the manual the only option that sticks out is HDMI RGB PC Range, never seen that before.
I'm sure you'll get it working, well 90%, what a pain is the ass if not, nice monitor that looks.
Have you tried it whilst playing any 4K movie content? I reckon the default UI etc. Only does 4k60 so it won't let you switch as your monitor won't do it, this restriction may lapse when the Xbox is already at a lower refresh though I'm not sure how you'll make the switch without entering the menu....
Alternatively find a way to change your monitors supported resolutions table, so this Xbox thinks it does 4k60 then see what happens.
Edit: that's exactly what it says in the link? http://support.xbox.com/en-GB/xbox-one/console/error-selecting-4k-uhd-resolution-xbox-one-s
You can't do anything but 4k24 over hdmi with your monitor and a 1s, which you can only enable once content of that refresh rate is onscreen.
Buy an hdmi to display port adapter and get 4k60 would be my recommendation.
