Nope, all FALD LCD TVs produce halos which OLED doesn't do
Well my tv isn't a LCD and I have yet to see any halo'ing on my screen.
I said it's on par, not better or not worse. From what I saw there wasn't much difference in the blacks in both screens.
If an OLED screen isn't set up right then it can crush the blacks and lose detail, mine was like this at one point, but after calibration it looks amazing. The only downside is with a bad source it will look rough, Sky is awful and looks all blocky in dark areas, but blu-rays look incredible.
You are probably right but spending a few hundred on someone to come in and calibrate it is something I can't afford at the moment.
I was torn between the LG and Panasonic sets, in the end I went with Panasonic and am more than happy with it. So far everything I've thrown at it looks immense to me ie blue rays, sky hd and uhd as well.
