HDR extrasDolby Vision IQSamsung's 2015 SUHD HDR playback on the reviewed 55-inch set. HDTVTest found bright highlights but the edge-lit screen had less dark-scene control than Samsung's full-array JS9500; no peak-brightness figure is transferred to other sizes.
Colour range–Nano Crystal quantum-dot colour and 10-bit panel on the reviewed 55-inch model (HDTVTest). Samsung's launch announcement positions JS9000 within the SUHD range, but does not establish an identical panel across all three sizes.

Picture processingAI Picture Pro, AI HDR Remastering, Brightness Booster; 77″ and 83″ add Hyper Radiant Colour Tech (up to 3.2x peak brightness)Samsung's global SUHD announcement describes Nano Crystal colour and HDR. HDTVTest identifies Smart LED edge-light control and measured 91% DCI-P3 coverage in Movie mode on its 55-inch review unit; this is a reviewer measurement, not a maker value for the line.
Picture modesFILMMAKER MODE with Ambient Light Compensation, Creator Original modeMovie mode was the most accurate preset on HDTVTest's 55-inch test set. The UK quick guide confirms active 3D but says glasses must be bought separately.
Motion handling–HDTVTest measured 1080 or more lines of motion resolution with Auto Motion Plus on its 55-inch unit and found LED Clear Motion strobing sharp but possibly flickery. It reported mild judder in 24-frame 3D.
Viewing angle–Both full 55-inch reviews found the picture faded away from the centre; the curve did not correct this limitation.
