I doubt that since you seem to need to enable 240 hz manually. Did some further testing and this seem to be related to what scaling options you have selected, with display scaling you can select 4K but no matter what other scaling option you select, it would always scale up to full screen (even though it is the wrong aspect ratio) and made it look as bad as you would expect. With GPU scaling 4K isn't possible.It should support 3840x2160 @ 240 Hz out of the box according to the manual.
