Despite it's offtop here - about 10 years ago was 4:2:2 MPEG2 permanent SD channel MED OFFICE on 39e satellite MED OFFICE.ts (10MB) https://yadi.sk/i/NnRontXRs-xckA - I knew only Elecard could decode it that time.
First race of FormulaE in history was translated from 4:2:2 feed - I've remuxed it with mkvtoolnix 09-13_13-19-15_hy1_-002.mkv (126MB) https://yadi.sk/i/G7KrUACkbUYEU
Eurovision 1920x1080i50 feeds was MPEG2 and now h264 but always 4:2:2
In some years international F1 feed from 10e is transmitted as h264 1920x1080i50 4:2:2 (namely when F1 - other events of weekend are in 4:2:0 chroma subsampling) i.e. 4:2:2 20190414-090034_TATA WIF Main_КвятКитай.ts (19MB) https://yadi.sk/i/XqdkpfKMddC_vA
In some month if I remember correctly from 4e9 was transmitting 3840x2160p25 4KUA channel 20171204-234107_4KUA.ts (55MB) https://yadi.sk/d/bo-0KiV83QKoge - only MainConcept HEVC Video Decoder can decode all 25 frames per second on my old and weak Athlon II x3 460 with ~90% load of each core, LAV Video Decoder stutters with 100% load.
Later I saw just seldom feeds like h264 1920x1080i50 4:2:2 09-16_14-29-23_LEV VS VAL HD50_.ts (62MB) https://yadi.sk/d/2lXjVe2S3MxFXG (my processor is quite enough to decode all 50 fps with ~50% load) or h265 4:2:2 3840x2160p50 20180428-175510_4K ENC 3 RMAD VS LEG.ts (563MB) https://yadi.sk/d/m0s5ztpj3XnUyw - I believe few processors (begining from Intel Core i7 and top AMD Ryzen) can decode all 50 frames per second and keep video and audio synced. I watched it with MainConcept's SkipPB option or with MPC Video Decoder with "Skip non Intra frames" in Properties of MPCVideoDec_skip_non_I-frames.7z (7,2MB) https://yadi.sk/d/ZBA-K2-6UUV4TQ with synced audio and ~1fps

Thank you very much - I've got well enough (some cool) colors while playing HLG in DGIndexNV:
