LG OLED65B7A TV (4K + HDR)
On the netflix and amazon app, playing a 4k HDR source will show on my TV "HDR" in the top right corner when the stream begins. This is how I know HDR is active. Without it, it will still play in 4K but without HDR.
In Plex 5.1.6 on Roku Premiere+ (the exact same setup as what works flawlessly in Netflix and Amazon) - the HDR does not show. So although the 4K sources appear in 4K, AND they appear without artifacts now after a recent update (thanks!), the HDR is still not functional. I have set the source to direct play, but still nothing. Any other settings to try? Or does this require another update by the Plex team?
