If 17 mb/s is indeed what the regular AVC equivalent would be, then that's teetering very close to the edge IMO. As you said, if the encode is tight enough then it can still give you decent results, but "good enough" is not what 4K should be aiming for.
That's why I'm hoping and praying that 4K BD becomes a reality because we'll be stuck with these bit-starved downloads and streaming otherwise. Which, like I said, is fine for content that's clean and sharp to begin with, but for grainier, grungier material it simply won't look as good as it could, which is why I'm wondering if the some of the movies on 4K unlimited are being done a disservice.
Yeah, 17 mpbs (BD equivalent) is cutting it pretty tight on the low end.
Who knows if and when 4K BD will become a reality. From what I've read
it'll be a couple of years before everything is standardized. In any case there won't be a lot of content and it may not come to Blu-ray if the market is too small to justify it. Besides the studios all seem determine to plow on to digital and they may use the new standard as a trojan horse for digital (where they will have more control over copy protection and distribution, both extremely important aspects to them).
If 4K makes it to disc, then it will likely be a hybrid system where storage will be a disc but that the player will require an internet connection to play it (just a sniff of internet will do, to authenticate), as well as more stringent copy protection schemes (such as those outlined by Sony
themselves). The studios remember they were promised better copy protection for BLu-ray and they got burned when it was cracked almost from day one. That coupled with lower than expected sales will make it a tough sell to studios, IMO.
It would be a dream to get "blow your socks off" UHD discs in a few years, and I'll be ready if/when it happens. In the meantime I'm happy biding my time when what we have now, which is certainly better than nothing.
