I believe you both misunderstand the meaning of the term "bandwidth".  
It refers to the RATE of data transfer, not the total amount.
So indeed, you can download the same size file with an arbitrarily smaller bandwidth, it just takes longer.

And to the broader point, it ISN'T the same video file, current 4k streaming is massively compressed vs. what UHD discs provide.
As another poster stated, the (playback) bandwidth rating 4k streaming is roughly similar to normal Blu Ray discs.

I've heard that the sales curve for UHD TVs and the like is significantly outperforming original HD TVs.
So curious how that reflects oh UHD-BD.  Could very well be that HD was not considered worth it, while UHD is.
And it also is due to profiteering by media companies wanting to charge premium prices for BD, and now UHD. 
I think there will also be a future dynamic from if streaming gains enough, physical channels will want to compete more.
(and the ultimate potential profits from price-gouging UHD-BD discs becomes less than if charged reasonable price to larger market)
So they might very well insist on getting UHD-BD discs at non-price-gouging prices, to better compete with streaming.
And at that point, media companies may well play along, so that they will not be prisoner to streaming oligopolies.

I've read that UHD discs are outperforming Blu Ray Discs in the same time frame. 

But you can add me to the list of buyers now. Yesterday I purchased a One S for $215 and also 6 4k movies.

Was gonna wait till Scorpio, but figured, what the heck. It was a good deal and I can trade in One S for a hundred bucks or something for the scorpio if I want it. ONly reason I got One S was for the 4k player, so doubtful I'll need to upgrade seeing as I don't play many ps/xbox games at all.

That was only mentioned in the first few months of UHD releases, it's been quiet since June.

That comparison was made against the first few months of blu-ray where
- Initial blu-ray players were $1000 or more, vs UHD players that started at $400.
- HD DVD had already launched earlier and was more affordable.
- 1080p tvs were only just coming out while 4K has been on the market for several years and is already much cheaper.

Then when the ps3 came out things changed drastically and HD-DVD was pretty much done despite stunting with upto 10 free movies included with players and selling the movies for less than dvd prices!


XBox One S has been selling very well, however not a peep about any uptake in UHD disc sales...

It's a shame, I love the superior quality and extras that discs deliver. Yet 4K UHD seems a half assed effort from the get go. Disc size only doubled, compared to over 5 times from DVD to Blu-ray. Max Bandwidth also only doubled, compared to over 5 times from DVD to Blu-ray. (Step from mpeg2 to h.264 is about the same as h.264 to h.265) Audio went from lossy 5.1 to lossless 7.1 as well as dolby atmos on blu-ray. No changes to UHD. Early 4K disc format promised 12 bit rec.2020 4:4:4 video, ended up being 10 bit DCI P3 (subset of rec.2020) with the same 4:2:0 chroma subsampling as on blu-ray.

It might be a big step from DVD and Netflix HD, yet coming from blu-ray, if it wasn't for HDR it would be kinda pointless. Of course there's no reason not to add HDR to standard blu-ray other than pushing for a new format and sell 4K tvs. A 1080p tv with HDR would look fantastic as well.

Selling 4K tvs with 4K UHD discs works as well ofcourse. It's the only (near) 4K content you can get.
