So you can do the math of 26 to 880 and
3.2 to 880 to see how much higher the compression ratio is for streaming HD currently with Internet delivery.
And that's likely going to remain the same for the foreseeable future. I don't think the ISPs have the capacity or the desire to provide bandwidths large enough to support 26Mbps videos. And even if they could, they would throttle the connections.
If I desperately want to watch something, I'll watch it on Netflix HD. But if I want to really enjoy a movie for its picture and sound, I'll get the Blu-ray.
