I have an LG OLED and have never seen it go blank on any scene.

It just looks great all the time. Especially on scenes like you describe with a dark scene with bright highlights. Campfire scenes look great, space scenes look great. That's what OLED is best at.

If you're talking about ABL, I've only noticed the dimming on ads or powerpoint lectures that have fully white backgrounds, and I've been thankful for it at those times because I find all-white backgrounds too bright to watch anyway.
