Depending on what you ultimately classify as a failure, UHD could indeed become irrelevant pretty quickly. It's taken well over a decade to get a couple of dozen channels broadcasting in HD, and I see as many DVDs for sale (or more) as blu-ray.
Having just premium content available, be it sports or movies and handful of prerecorded media on offer, in my eyes does not equate to success. To be a true success it needs to be the standard for all TV/movie studios and production companies, but I would imagine budgets may have to increase to accommodate that.
Given the massive uptake of media streaming be it , YouTube, Netflix, or Amazon etc. which has dynamic resolution and is dependent on bandwidth rather than traditional delivery methods, I would think feedback and demand from the users of these services will play a big factor in deciding the success of UHD.
