A:Answer These are different issues, as the resolution doesn't have anything to do with HDR. The set does upscale standard and HD content to be more sharp, with the set estimating gaps between pixels in lower definition images, which works fairly well. Occasionally you can notice some hazing at sharp contrast lines in the images. Very minor though.
The HDR for the TV is a read and display HDR, so if playing content that is designed to display in HDR, it will. It will not upscale images to HDR though. HDR is a post processing image quality where the photo, displayed in 4k, is shown with exaggerated contrasts, by selecting the detail rich areas of bright and dark sections of the image, and exaggerating these details so they aren't washed out by the exposures. More expensive sets will use different exposures of the TV stream to "upscale" content not shown with HDR programmed in.
