Hello have a question about 4k streaming from netflix?

Is the 4k quality really so much worse all those of 4k bluray filming? I've bought a 4k tv and found the 4k hdr quality hammer in the net but it is not so good compared to 4k bluray I was thinking of me to get a 4k blurayplayer but the 4k movies I think are extremely expensive worth the Expenditure?

Well… For one, the data rate is a lot (!) Less streaming. On the other hand, this is also because here is a simpler H.264 codec is used, which encodes the colors with only a quarter of the specified resolution (4: 2: 0).

So you have the 4K streaming the color channels actually only in full HD.

All so you have 4k streaming but with a slightly worse quality compared to bluray 4k

So I know the quality differences only when comparing SD content in television and DVD. And there the difference is huge. But I guess at 4K it will not be so blatant.

Whether you see a difference in quality, of course, depends on the distance to the TV and the TV screen diagonal.

In addition, of course, there's also the question of the content, often what is offered to us as 4k is not really 4k QHD also known as 2k.

UHD = 4K = 3840x2160 pixels (in the cinema even 4096 horizontal).
QHD = 2K = 2048 x 1080 (but is often praised especially for streams as UHD / 4K.

Then there's the matter of compression and bitrate, most UHD streams are running at bit rates around 17.5 MB / s, whereas good UHD BlueRay bitrates of 35 to 70 MB / s, so there are small ones worlds in between in quality.

The problem is that most people in Germany only have televisions up to 65 "at present, but only over 65" does that at a normal sitting distance to the TV, a really visible difference.

and the biggest visible difference is HDR, but unfortunately there's still very little content left.
