I also purchased a 2015 75" Samsung 1080P set, model J6300. I moved up from an 8 year old 61" Samsung LED DLP 1080P set. While I liked the picture it provided, advancements have clearly passed it by. I didn't realize black could be so black and still have detail. The extra picture real estate is also a huge plus, the main reason I got it other than the fact the DLP was on it's way out again. A 75" for under $2k was also a big selling point, 4K wouldn't provide any added benefit to me.
