What are using to stream with, if I may ask? For the most part, I'm using the latest Roku Ultra, model 4800 I believe, and I do notice a difference in both picture and sound between the Roku and my Sony X800, although the Sony doesn't have Disney+, so I can't compare an apples to apples comparison between the two streaming devices. But on other platforms like Netflix and Prime, I would give the edge to the Sony, both in picture and quality, which makes no sense since it's just bits that both are outputting.
