I never stepped up to blue-ray. I have many music CD’s and movie DVD’s. On a large screen I have no complaints about DVD quality. Some Blue-Ray movies I have seen on other TV’s look too crisp, almost as if you can tell its a movie set or CGI. The lower definition of a standard CD looks more like the real world to my eyes.
Blu Ray is old technology and looks unimpressive to my eyes. You don’t know what you are missing until you have seen 4k Blu Ray (UHD) on a large OLED screen.
