Was there anything in particular I should be looking for? The display function on the PS3 showed 240 SD/480 SD, then 720 HD...I was about to give up then at around the 5 min mark the display showed 1080 HD and remained there for the remainder of the segment.
I had just streamed, on the PS3, episode 2 of Wallander. After the first minute or display showed 1080 HD and the picture was really good. A few scenes with fog that looked terrible near the end though. I mention Wallander because this is one of the series in my queue that was "HD" on my Roku and now is "Super HD" since a couple of days or so. I don't know of a way to display the streaming resolution on the Roku like you can on the PS3.
I hope this helps with the information being shared on this thread.
