Samsung had a SUHD displaying HDR content, right at the front of its large stand. Given the display´s support for HDR10 we can savely assume that Samsung was using some created for UHD Blu/Ray content. Eventhough it had previously tested with and expressed its full support for the BBC R&D Hybrid Log Gamma system.
French compression vendor Ateme was showing off the Philips system, but the open booth demo using another Samsung curved SUHD TV that I was told was showing the HDR output from its TITAN File encoder in Blu Ray Encoder mode.
