If you're refering to the blu ray I would say the difference is quite substantial. For the GOUT the differences are smaller (especially in the first screenshot), but you can see that Darth Vader's mask in the second screenshot is much less blurry in the details for the super resolution upscale. Other examples are the commanders face and hair in the same screenshot. I will post some screenshot comparisons where the differences are more substantial.
