Good post !
“Is it worth the cost?”
Cost has never been a factor for me. Just has not. What has always been the “hold-back” is poor upconversion. Never comfortable with what upconversion did to 2K broadcast live sports.
Maybe 2021 and the beautiful A90J. And a more modest size might look better with that upconversion. Sure 77” or 82” would look spectacular with 4K HDR.
Upscaling on the LG is right on par with Sony...I've also owned Sony oleds. However the Sony price justification from the fan boys will always portray the LG as if it were garbage...its their money though so can't argue with that. IMHO a smart savy buyer will take their time and weigh whether or not the Sony is actually worth that premium. I don't.
