I'm not sold on the local dimming issue ,for what those units cost Vs what I have now ...Hmmmm
but I'm happy with the blacks on the 632 80" with Suzook's settings I get deep blacks that are Not crushed & get a brighter image , add in the 80" size factor , the 632 80" costs outta US Appliance , add all that up in trade-offs for & against Local Dimming . For Me, I made a good choice, that I do not regret .
But what Floats my Boat might Not blow your Dress Up

I'm glad that there is choices, trade-offs
