Sorry to intrude in your thread but HDR is just the default output from the box. Its only beneficial for 4K HDR TV’s only when the source is HDR as well i.e Netflix or Prime. The DTH picture quality is good/better than the HEVC HD boxes but it has nothing to do with HDR , as SDR content (DTH) cannot be converted by the box into HDR. The box is upscaling the picture to 4K to offer better picture for 4K tv’s.
As for HDTV’s also the picture quality is better.
