Well there is vertually nothing in it when viewing at night, in bright daylight there is maybe a tad more detail in dark areas but only in very bright daylight.
This is obviously the direct colour filter 3 at work on the 08 that makes the difference.
However it should be noted that the 5080/6080 screen is LESS reflective.
Once calibrated all the difference I can see is a slightly stronger red and a tad more depth to the picture, but you have to look very closely and you will only see this if the models are seen side by side in the right environment. Even then you have to look at the sets for about half an hour to really see that difference.
If you had either of these models on their own you would be happy.
