Yes the picture quality is better provided you have a 4K HDR television. For absolute maximum fidelity find yourself an OLED tv. Besides the upgrade in picture quality, the quality in sound to me is vastly better on a blu ray than on streaming. Since the audio has to be compressed over streaming it gets dulled out but on a blu ray you have the true audio mastering of the film. Make sure to get a good audio system for it. I personally have a 4k Sony television with HDR and a high end Sony sound bar with the wireless surround speakers and subwoofer. I do a lot of movie watching and have a collection of over 100 Blu rays. It's expensive but if you enjoy watching films than it's worth it.
