No, it cannot be trusted. The Sony has brighter best modes and darker blacks, much brighter. If comparing to the Panny, the Epson 5010 is better if wanting an LCD, or the JVC if wanting an LCOS with darker blacks.
For blacks, the Sony's Native On/Off contrast maxes near 10,000:1 even if you just close the IRIS at farthest throw without the dynamic IRIS in action. The Panasonic 7000 in Rec709 Mode relying on the IRIS only gets to around 8,000:1 on/off (again with the IRIS). If you turn the Dynamic IRIS mode on for the Sony, then the max on/off approaches around 15,000:1 to 20,000:1 or so starting from 5,000:1. Only the Panny's cinema mode IRIS can beat that, but it's too bouncy.
Overall we are talking an easy win for the Sony in brightness and a small win in black levels for the Sony.
The Sony has the better pixel fill, even though the Panny has smooth screen. I'm not sure which one is sharper, guessing they are about the same, Panny might be slightly sharper don't know. The Sony most likely has less ghosting in 3D.
