HDMI should support proper EDID negotiation, so if your TV reports 2160p at 24/25/30 or 24/30 then the source should only send content at that frame rate and shouldn't try to output 2160/50p or 60p.
All 'movie' (and TV drama/scripted comedy) shot 4K is likely to be 2160/24p (or 25p if European TV) so that is unlikely to be an issue.
What WILL be a potential issue is playing 2160/50p or 59.94p content - which is likely to the the standards for UHD1 TV broadcasts via DVB etc. You'll get these downscaled to 1080p or frame-rate dropped to 25/30p I suspect. Nothing that can really be done about this - but it shouldn't stop any 4K/60p boxes working with your display assuming the source is properly HDMI-compatible.
