4k content is best streamed and with little to no loss in quality \n\nIt's hard for me to take the article seriously after reading that part. Even with a 2K projector using a scaler device, it's obvious how much sharper and more perfect the images are from a good 4K UHD disc than even better streaming sources like iTunes. Look at the grain clarity in a film conversion. iTunes is smoothed and UHD discs show perfect grain patterns. DTS:X (I own 54 native movie titles) and Auro-3D titles (I own 27 native movies and a dozen or so music albums) are only on disc thus far so there is more than one reason to go disc.
