Colour rangeSamsung's UK tables say 100% colour volume by Quantum Dot and a billion colours; these are maker claims rather than measured coverage for every size.Samsung's 2017 QLED launch claimed 100% colour volume. Les Numériques measured strong colour on its exact European 65-inch unit but found its Cinema-mode colour error above its preferred threshold; neither figure is assigned to other sizes.
Picture processingQuantum Processor 4K, Ultimate UHD Dimming, Intelligent Mode, HDR tone mapping and 4000 Picture Quality Index in the UK maker tables.

Samsung does not publish native Hz for both sizes in the UK tables, so the main refresh row is omitted.
