As far as I can tell almost all of the HD titles have 1080p encodings. There currently being 3580 of them, I haven't checked them all
, but I did check 30 at random once and they all had 1080p encodings. Since then I haven't personally found one that didn't in my regular watching of HD titles, though a few which didn't have 1080p encodings were pointed out to me. (A few seasons of some anime series, for one, where some other seasons of the same series did. Another title limited to 720p for some reason is Scary Movie
When they generate the encodings for streaming, they create several at 480p (and, if they're allowed to offer the title in HD) two at 720p and one at 1080p. My guess is that they always generate a 1080p encoding for HD titles unless the IP holder forbids it and I imagine that they might not generate one if their HD source for a title is of poor picture quality. Now 5.1 sound has more limited availability. It seems to be running about 25% of the HD titles (there've only been a couple of titles with 5.1 sound which did have HD encodings).
In many ways the issue is the same with TV broadcasters who never, as far as I know, broadcast in 1080p.
The ATSC standard allows for 1080p24, but you're right--no broadcasters that I know of have chosen to use it. It might require more bandwidth than they're willing to give up (though intuitively it seems unlikely to require more than 1080i30); maybe there are some televisions that can't handle it (probably the issue). 1080i30 and 720p60 is what they've settled on. BDs of HDTV series are generally encoded at 1080p24, just like movies.
Is your Roku a Roku 2 XD or XS? None of the other Roku models can display the 1080p Netflix encodings; I'm fairly certain that ATV and LG BD players can't either (a couple of recent model LG LCD panels had a firmware update which added that). AVS Forum member RangerOne has been keeping track of devices whose Netflix players do have 1080p in his techofthehub.com blog, in this
