Watching Football on TV (LED/OLED)

Disregard the hurricane damage, LOL. That is a 65" on the wall. My wife doesn't want to let me get the 77" because she said it will be "too wide". It would leave 2.5" on each side from the edge. I disagree with her. It would be the width of the mantel. Would it really look weird to put a 77" up compared to the 65"? is $2900 too much for the LG C1 OLED 77"?

$2900 seems a bit high when a 65 can be had for just over half that. But, I guess that's the going rate for the 77s.

The 65 seems to fill out the space pretty well. Seems like the 77 would be wider than the mantle and might make it look a little off. But, if you get a much better viewing experience, worth the tradeoff imo.
