I went and viewed the 70" Elite. It replaced the former spot for the Sony 55" 929.
The other HDTVs were behind the seated viewers.
The dedicated Blu-ray source was carefully chosen and not showing on any other display. Sharp is pays for this privilege to prevent direct comparison to other displays (all showing the crappy house feed).
The Blu-ray had very little panning of scenes. Backgrounds were mostly out of focus. This helps to prevent observing screen non-uniformities (Dirty Screen Effect). However the Elites may be getting a binned panel. Pioneer claimed to do the same thing. There is probably more total LEDs than the 735 too.
However the Sharp main weakness and compared to the 735 is the hugely reflective glossy screen. All the other background displays were embarrassingly visible on the Elite. The reduced contrast prevented any critical analysis. This indicates that the Sharp 735 is much better suited to typically bright family rooms. The Elite is better suited for darkened rooms, which is a darn shame, as it has a
very wide dynamic range. I think glossy screen is a fatal blow. Sharp threw the baby out with the bathwater!
