From a technical standpoint, the 4K UHD releases of Season 2 are a showcase for High Dynamic Range (HDR). Analyzing the HDR10 metadata via FFmpeg ( ffmpeg -i file -c copy -bsf:v trace_headers -f null - 2>&1 | grep " mastering" ) would reveal a significantly wider color gamut (Rec.2020) being utilized. The candlelit scenes in Versailles utilize the ST.2084 PQ curve to display brightness levels that simply cannot be represented in SDR. The gilded gold in the throne room actually "shines" with meta-data driven luminance, a detail lost in standard web streams.
In Season 1, the 'V' channel was often suppressed, leaning towards greens and cyans to mimic the cold Scottish damp. In Season 2, specifically during the grand ball scenes, FFmpeg’s histogram filter would show a massive spike in the upper range of the 'V' channel. The show utilizes rich crimsons, deep burgundies, and gold leaf. outlander s02 ffmpeg
