The Harmony is much more off the wall than the Eclipse, even with the wall bracket. But hiding the screen behind the panels when switched off is shrinking the visual size of the TV more than I had expected. A 65" Eclipse is much more present when off. Comparing both TV is an large showroom did not show this expect compared to a more standard sized living room at home.
When on, the 65" Harmony is big, but when off I always think 77" could also be an option...
Also the Harmony can be upgraded to larger screen or newer model from LG much easier, you just need a new bracket. Also you could go with the heavy discounted C9 or CX panels instead of the GX panels which are more expensive and might not see the big price hit as the CX range.
With the Eclipse this is more a theoretical option.
And the Harmony is heavy...just to move a little bit left or right or to the wall to adjust or connect a cable. Big task.
