I have late 2014 5k retina Imac (running Sierra). Does it display HDR video (from a video editing application for example from FCPX or Premiere) ? I don't really care about you tube but that would be of interest also. Don't care about NETFLIX but my understanding is because of DRM you can not view HDR from Netflix on any computer anyways. If not late 2014 models what newer models can display HDR? Macbook Pros models display HDR?
