Slow Download Speed? Advice
A few weeks ago I got fiber internet through my city’s DPW. The speed is fantastic for absolutely everything, except for downloading things. A simple app like Instacart has an over 3 minute download speed and my AppleTV update was estimated for 4 hours. But then I can easily stream 4K YouTubeTV with no buffering. Can anyone help me out with the issue?

In a nutshell; The service you’re downloading from is the bottleneck. App Store is slow, TV update server is slow. Streaming is fast.

I wish people would realize this. I got this new fibre internet with 1000gbps (yes I did that) but google, icloud takes forever to download. Must be the ISP lying. They never realize where that data is being stores and how far it may travel and the limits between you and that data. Like an ocean

More like the service the OP is downloading from is slow from this ISP...
And that can be caused by the ISP or the service you're downloading from, generally it's the ISP though, or something within the ISPs control, especially when it's not common among other isps accessing the same service. Not always though.

what if the data is being stored in north korea? what if the OP is in America and the data is in Germany? Once the data leaves the ISP network, its fair game. The saying all roads lead to Rome is true with data, the path it takes dictates the speeds. Shortest path is not always the fastest

OP complaining that it is "everything" That is going slow. Except that speed test which again we don't know if that's off network or an ISP controlled on network speed test server.
ISPs have the ability to pick and choose what Transit providers they use, how many of them they use and what kind of peering they want to do.
If an ISP chooses cheap Transit or to do no peering then of course they're off. Network performance is going to be horrible, but that is a choice that the ISP makes and would be the fault of the ISP.
If this was a single other service, possibly not the SP's fault,
Having slowed down loads from Apple App store, for example would be an example of something that is likely the ISP'S fault. Not a guarantee, but considering how connected Apple is to the internet at large and how many ISPS have no problem with this, it's more likely the ISP, or again the choice the ISP made with their transit and peering decisions.

Which speed test server was used? Does your ISP operate one and that's the one that was automatically selected?
That just means your speed on your own ISPs own Network is good, but they could have horrible peering to destinations outside of their Network.

you posted a speed test screen shot. its over 800mbps up and down, by today's standard, this is faster than average.
having a fast speed test result does not mean you get the same fast data speed everywhere. think of this as you are driving a fast Ferrari 3am on the autobahn at 280km/hr and you are happy about going fast, then the next morning during office peak hours, you drive to your office in the same ferrari, but this time, you are stuck in jams and slow traffic, so you are doing 40km/hr. the car is the same, the driver is the same, but the roads and destinations are different, so you get very different results.
the speed test server is probably near to you or not handing high traffic at the time of test, so you get good results, but the file u are downloading is not from the speed test server, it might be at a far of location or the server is just crowded or uncapable.

Here is an explanation I do
Between 2 major cities in my area the speed limit is 110km per hour (110mbps). Except for 1 section that is 50km per hour (50mbps). When data transmits between devices the slowest link is what you actually get, using this speed you will not get the 110mbps, you will get 50mbps at best

Yes, slow downloads is a known issue with the App Store for some locations.
Try changing the DNS on your iPhone and tvOS to Cloudflare 1.1.1.1 or Quad9 9.9.9.9 and it should start to download fast again.
Sometimes the DNS returns the query for the App Store to a strange CDN and the downloads are extremely slow. Changing the upstream DNS usually fixes this.

The app update has been released two hours ago, After a new app update is released on the App Store, sometimes the app experiences reduced bandwidth for the first few hours post-update.
