I contacted LG team regarding web os update, they said only firmware updates will be given, No webos upgrades
I have an 2016 43lh600t and my web os is 3.3 and firmware version in 5.xx.xx.When contacted hotstar i was told it only supports tvs with webos 3.5 and above since their platform is not compatible for webos below 3.5.☹️
