I have a 65 of this P Series. It is unbelievable in a dark room. If you're looking for a tv in a well lit room, this is not the one. But in a dark room, best bang for your buck bar none.
I have the 75 inch version - excellent screen quality and display.. i paired it with an 4K Blu Ray player and the picture is fantastic. The tablet is slightly annoying but I use my Tivo for netflix / Hulu etc.. instead of using the tablet.
