LG 65UB9800 and Mac Pro

I am about to order LG's new 65 UHD TV to use as a monitor for nMP. It has HDMI 2.0, so I am assuming that I will be able to use it @60hz down the road when nMP gets some kind of HDMI 2.0 update. Is there any reason not to buy this TV now? I am also assuming that I could run this at UHD@30hz right away, am I correct?

Thanks.
