Flat panel technology according one scene in Passengers.

Hello to all forum members. I'd like to know your opinion regarding an issue I noticed yesterday while watching Passengers.
At the begining of the movie when the big asteroid impacts the shield of the Avalon, there's a scene where one can see a room full of crio pods where passengers sleep during their journey, at the impact time this room gets totally dark with just some small but bright lights from the pods. On my new one month old Samsung T.V. set, a 49'' mid price (800€) 4K HDR set, there were NO light bleeding on this scene. I went back and checked again, went back and paused the scene and nothing, just a plain black screen with no light bleeding from the pod's lights, zero, nada. This surprised me, my previous Philips SDR set, which sits upstairs now, has some light bleeding, all of my previous T.V. set suffered of this on some degree, it looks like the inexpensive Samsung doesn't.
I think the panel may be an Edge Lit, but I'm not sure. On its specs the set mentioned something about micro dimming or local dimming, but I read sometime ago that Edge Lit panels are incompatible with this technology. I have no idea if this is true or not.
My Samsung T.V. set is an European model with limited HDR specs, it looks fine for the price I paid for it either with HD, broadcast T.V. and 4K HDR, but it's not by no means the best set out there.
What kind of panel technology according with what I just told you can it be using?
Thanks in advance.
