Finally got the LG QNED82BXA instead of TCL C6K / Q6C
After searching for 15 days across platforms, I found the LG QNED82BXA at the same price as TCL Q6C. Additionally, got 3 years warranty instead of TCL's 2 years. Did a lot of reading, lot of user experiences and found that screen issues with TCL are quite common. Didn't want to take a chance with 50k, so went with the better brand.
