To update, got a Sony X95G 65" to satisfy my brightness cravings (this time around, i auditioned the set before taking the plunge). This particular TV is a 2019 model and inventory is difficult to come by but i managed to track one down.
The TV is a gem. HDR brightness is kickass and really makes images pop. Its a shame Sony did not release its successor - the X95J. HDR brightness is in fact a good 200-300cd/m2 higher than Sony's current flagship in India - the X90J.
Was installed yesterday and had a few friends audition the set. Unanimous consensus was that the videos i played (movie trailers on youtube) were more immersive/captivating/impressive on the X95G than the G1 OLED.
Colour me content!
