Yeah, it's definitely depends on your cable provider or the company that distributes the VOD content to the cable system (with Rebels, usually the next episode is available a day or two after the newest broadcast but sometimes it may take longer for some systems).Funny, I found "Rebel Resolve" on demand just today (and bonus: no commercials!). I guess different VOD services release it at different times?
I recall the "VOD advanced look" happening to occasional episodes of the Marvel animated shows on Disney XD in the past, but I'm not sure if they've been doing that at all recently though. It's been pretty much the case with Rebels since the start, though.
With the exception of news, sports, & marathons of various shows, pretty much everything else I watch VOD.This VOD thing is amazing! I had no idea I had this! It has brand new episodes of all the major shows! Sometimes my DVR glitches and doesn't record things and I have to watch them on Hulu on my computer screen but now I can just watch here on my big TV! They even have some free movies on there (mostly crappy ones).
