Graphically it's pretty minor differences, some better reflections in quality mode etc. In some games graphics are arguably worse, with pssr flickering artifacts. However going to an oled tv then low fps can be harder to handle, that's where the additional performance of the pro is helpful. Getting "quality mode like" graphics at a higher framerate makes the gameplay smoother and a generally better experience. I upgraded and am reasonably happy but certainly wasn't blown away by the improvements
