Today, sometime back, while browsing through Hotstar app on my Airtel Xstream stb, I found the HDR icon/logo for some titles for which it was HDR was not found after recent update (Ver 2.2.3). When I played them, the TV is detecting HDR and HDR logo is appearing on top right corner of my LG TV 55SM9000 and accordingly HDR picture modes are selected. When I click back on remote, it's coming out of HDR picture modes and is back to normal picture modes. This happened for Avengers : Endgame, Togo.
Also, I checked Amazon Prime app also. For Jack Ryan too, the same thing happened. HDR mode enabled while the series is playing only.
Also on Netflix for Lost in Space too.
Was there any change to firmware or anything happened today. Did anyone notice it on their TVs too.
Attached are few pictures.
