Compression. While Compression tech HAS improved, its been maintaining our current quality while reducing bandwidth needs.
A 1080p Bluray disk will look far far better than Netflix in 4k every time because its not compressed. The reality is that any form of compression will cause loss in fidelity in some way, so the only way to really improve video is to increase the bandwidth of the video.
I talk to IT nerds frequently who are asking things like “why do you need 16x 400GB ports of non blocking bandwidth” to which I have to explain that a SINGLE stream of uncompressed UHD is 12GB/s and we are trying to put 200+ streams onto their network.

You’re not wrong about the quality difference but video on a Blu-ray is compressed. There is no way to get raw video unless you’re shooting it yourself.

Lossless video compression also exists although I don’t think any consumer products have it.
Diminishing returns. It’s already hard for many people to see the difference between 1080p and 4k. The difference between 4k and 8k is almost nonexistent at significantly higher storage costs.
As others mentioned it’s diminishing returns, but there’s still a lot of good innovation going on in the codec space. As an example - the reduction in the amount of space required for h265 compared to h264 is staggering. Codecs are a special form of black magic.
Because the details get harder and harder to notice the difference.
I mean, I have difficulty seeing the difference between Blu-Ray and DVD, maybe in some cases if some effort were to be put in. But even so.
1080p and 4K? Barely can tell.
Things like going from VHS to DVD, yeah you can tell significantly. 360p to 720p to 1080p? You can tell, less pixelation.
Now I understand that it’s all about being great quality in greater resolutions, I get that, but really I don’t get the big freaking deal for 4K and 8K and all that.
Honestly I’m not sure I completely agree, we’re pretty close to a perfect TV with new LED technology.
But maybe we’re talking about a next stage here, like true 3D or something else like smell? I’m not sure what the future will be, but TVs look pretty good to me and I’m not sure what perfections the current ‘variant’ needs.
fullHD already looks pretty good
actually transfering all the data is a problem, like my wifi struggles even with streaming fullHD sometimes, so 4K is just unusable (+ you need a more expensive screen to actually show the 4K which I don’t have either)
Diminishing returns.
4k on a 75in and 8k on a 75in isn’t a big difference.
Not to mention most streaming content is 1080 for bandwidth and tvs upscale to 4k. So while there is difference, it’s hard to quantify upscaling, and even if you find a store with displays, they’re being fed native 4k.
If you go to rtings.com or a similar site you can compare specifics and see that there is advancement happening.
It’s just not like back in the day when they could keep doubling resolution.
On top of that regular TV broadcasts tend to be 720p/1080i
1080p is enough for most people’s eyes. What do you want?
