These things aren't for use in an office setting where you're fiddling with a web browser, Excel, or writing software. They're for situations where colour calibration matters, so either designing for print, or working on video.

Particularly for the people doing video an 8k display is great - that means you can have full resolution 4k video on screen with space around it for a user interface, or you can have a display with the 8k source material on it if the film was shot at that resolution.
