It's a big jump, more than the resolution increase itself would require for equal quality. 2.5k video is about 8-9mbps and 4k video is about 16-18mbps (these are all for VP9 streams). Well it gets a lot better at higher picture sized. More bits = more detail in compression, regardless of how many pixels. That's pretty crap, considering Blu-rays are usually more in the realm of 25mbps at the same picture size. For 1080p30 it uses a bitrate of about 2.5-3mbps. Youtube is pretty aggressive about the bitrates they use to save on bandwidth costs and play on a wide variety of connections. However another, probably more important part when talking Youtube is just bitrate. So ya 4k video has 1920x1080 chroma samples. It is true that basically all video encoding these days is done with a 4:1 luma:chroma ratio. The latest hardware decryption features simply aren't available on older Intel processors, and the new Kaby Lake chips now support 10-bit HEVC, a popular 4K video codec. Content providers have strict controls for 4K playback, so that streams can't be captured and redistributed illegally. It all might seem like a bit of a con, but it's largely the fault of DRM requirements from Hollywood studios and TV networks.

As a result, Microsoft is using the 4K Netflix support as a marketing effort for its Edge browser and to encourage people to upgrade their hardware to watch new episodes of the Gilmore Girls. Netflix is only supporting 7th generation (Kaby Lake) Intel Core processors, and there aren't many laptops that actually support both the 4K display required and the new Intel processors.
#Netflix 4k windows 10 Pc
Netflix is now supporting 4K streaming through Microsoft's Edge browser, but you'll need a new PC to actually make use of it. While a number of TVs and set-top-boxes already support 4K Netflix streams, the PC has largely been left out of the high-quality streams due to piracy fears. An anonymous reader quotes a report from The Verge: Netflix 4K streaming is finally heading to Windows PCs this week.
