I would say that at first there would be a perceived difference on sharpness on the larger screen, especially if the two sets were side by side. Things will always appear sharper on a smaller screen, something will look super sharp on a 5” phone screen but softer on a 100” projection screen. However you will quickly adjust to the look of the newer screen size, and then the benefits of the new screen will take effect. Viewing the larger size will allow you to perceive fine details that you weren’t able to resolve on the smaller screen, like fabric patterns in clothing and fine facial details. Also the advantages of the newer technologies like deeper black levels, wider color gamuts, and HDR on newer sets should vastly improve the image quality over your older set. Once you get adjusted to the newer set going back to the old Samsung might surprise you with how much things have changed in a short period of time, it’s the best time ever for flat panel TVs!
