I'm having a real problem with my TV during dark scenes/night scenes etc.

Really bad halo/ring pixelation is showing and the picture looks really noisy.

I'll include photos from a recent blu-ray watch but it basically happens during every dark scene and for a 4k/HDR upscaling TV I expect better for BluRay and HD pictures.

One old post I came across suggested it could be a faulty panel?

Please help as this is driving me nuts!
