Hello community!

I am really interested at the KD-49XD8305, and correct me if im wrong but its a 2016 model? Anyway, isnt the 4K X-Reality Pro processor old? Why doesnt it have the X1 HDR 4K processor? How is the picture quality, i would really appreciate it, as im new to the Sony TV World. (Comming from a Philips 32PF9996/37 )
