I'm considering getting one of those LG 65" OLED TVs, after seeing one in-store and being completely blown away by the picture quality. Much like the GP I can't recall the last time I saw a display that actually wowed me, but watching a space shuttle take off, and bright stars as dots against a pitch black sky without the typical blue-ish backlight bleed, was just amazing. I stood there watching the same 4-5 minute video loop for what must have been half an hour or so. But your comment now gives me pause – the picture warps over time? Do you have any sources on this so I can learn more?
