Extra resolution is the headline feature of a UHD Blu-ray...but this may not be the thing you notice. NOTE - THE EFFECT OF HDR ...IS.....NOT...VISIBLE...ON...YOUTUBE WHAT I AM DEMONSTRATING IN THIS VIDEO IS THAT THERE IS A DIFFERENCE...HOWEVER YOU CAN ONLY SEE HOW THIS LOOKS IN PERSON ....ON YOUTUBE IT JUST LOOKS DARKER The TV used in this video is an LG 65EF950V (aka 65EF9500) - a 65" 4K HDR capable OLED with a 10 bit panel, HDCP 2.2, HDMI 2.0a. Notice when I said that I couldn't see a MASSIVE difference in resolution on a 65" TV when sat 10 ft away.....this is not the same as not being able to see ANY difference - It is of course noticeably sharper, but not MASSIVELY so. What makes a BIG difference though is the HDR..but this can only be appreciated IN PERSON. The intention of this video is to suggest that you don't just think of a UHD blu-ray as being a blu-ray with more resolution - because that's just one of the features and frankly quite probably the least interesting one.
