LG E6 TV, Comcast XG1v4 DVR, Roku Ultra & LG UP970 Blu Ray - Netflix, Plex & USB HDR results

Regular Visitor

LG E6 TV, Comcast XG1v4 DVR, Roku Ultra & LG UP970 Blu Ray - Netflix, Plex & USB HDR results

My bottom line was that the only way to achieve correct HDR from Netflix was to connect an LG UP970 HDR Blu Ray player through my Marantz preamp (which passes HDR10, but not Dolby).  This caused the UP970 to only accept HDR and not Dolby from Netflix (even though the UP970 has Dolby capability).

 

The UP970 Blu Ray player correctly decoded all HDR files from Netflix when operated in HDR and not in Dolby mode.

The UP970 did not correctly play some HDR files when in Dolby mode connected directly to the LG TV (too dark)

The LG TV correctly played all USB and Plex HDR files.

The LG TV native Netflix app did not play “The Crown” in HDR.

The Roku Netflix app did not play “The Crown” in HDR.

The Tivo Netflix app did not play any files in HDR.

The Comcast XG1v4 correctly decodes HDR on Olympic files

    (you have to search for “4K UHD on X1” to find files, I could not browse to any HDR files even with their support people helping me)

The Comcast XG1v4 did not decode any Netflix HDR files correctly.  The Netflix app must not yet be complete.

 

Here are my devices

    LG OLED65E6P 2016 software 05.30.02
    Marantz AV7702MKII firmware 0992-9380-8220-04 DTS version 3.90.35.00
    Roku ultra (current firmware)
    LG UP970 Blu Ray main version BD.39338.80123.c servo version UP17SON0017 Area Code US

    Comcast XG1v4 DVR (release version xappl-XRE83P7, XRE Protocol 2.8.0, STB version AX014AN_2.14p13s1_PROD_sey)

    TIVO Bolt-Vox (current firmware)

    Current Plex server on Windows 10/Intel i5, current version of Plex clients.  Files are HDR demos.

    The Netflix “test patterns” files can be found via search.  The last one “season 4 episode 4” is 2060P60 HDR10.  The important        

    telltale are two boxes saying “ST.2084” in the lower right which only can be read in HDR, otherwise they are blank white boxes.76444602-40A6-4BE7-81A0-23BC21ECC1BB.jpeg
