I have the EU equivalent, the sk8500, 49’‘ model. Although its local dimming is not perfect (noticeable in logo screens), in real scenes makes a huge improvement over the picture quality. Reading the review gives the impression that is not worth it but this is far from truth. Personally, I set it to “high” as this reduces blooming and I don’t mind if some very small highlights are a bit more dimmed. Also I will agree that bias lighting improves this function a lot!
