Also, from that same article: First, Apple hasn’t said how many 4K HDR titles it’ll have for purchase or upgrade, but we can probably get an idea by looking at other services. Vudu offers 121 movies in Ultra HD, compared to more than 24,000 films in standard or high definition, while FandangoNow lists 197 Ultra HD films, so it’s safe to assume most movies will remain in HD for a while. Disney has also indicated that it won’t offer 4K HDR movies on iTunes at all.

"So, your telling me there's a chance"? The way I read it, yes, UltraFlix can still get in there and grab some of the 4K HDR turf.
