Mr. Ravichandran, I share your pain and grief as I was a loyal LG customer for good 6 years. I have 3x 65" UHD LED TVs from LG as I always felt them to be very reliable and has good support until I moved to India. No support, no apps and it was like a dumb TV now. So, What I did was to buy Amazon FireTV Stick 4K for all my TVs and one Amazon Fire Cube 4K. It allowed me to download all sort of apps, has great features and very convenient to use. I totally ignored that my LG TVs are actually smart as they lack apps and upgrades usually available on other brands.
With the above experience, I ditched LG Brand this time while buying a New TV... and bought a Sony 75" 8K OLED TV. I did not even bother to look at LG. Although OLED panels are built by LG only but due to my experience with LG (not)SMART TV app support, I preferred Sony with (Moded) Android OS. It supports Dolby Vision and Dolby ATMOS and it is stunning. It natively support all the usual apps and the OS response is fast too. One thing I dislike with Sony TV is the remote. It is old style bulky with lots of buttons on it. But it works like a charm. See the attached photo and video where I am using it for my display with all the windows and Video on this beautiful High Res OLED TV.
So, in my humble experience, I would suggest you to buy the Amazon FireTV Stick 4K and enjoy all the apps and a very responsive system as LG is not going to get you the popular apps or much required updates.
