Oh okay, I get you - so in a heavily loaded area (i.e. central London), by using multiple carriers and CA, speeds will still be relatively good and the masts won't cripple under the heavy load.
So for example, you might get a decent 50Mbps with all 3 carriers, and carrier aggregation, whereas you will get less with 2 carriers and very little throughput at all with everyone on a single carrier?
Meaning that, as more people switch to 4G and 4G+ devices, the speeds will still be good and the network will be future proofed, rather than playing catchup.

Forget 4K video, I'm still using 1080p, 720p or even 480p, depending on what my laptop will let me do.
I guess that, as you mentioned, uploading and downloading rather large files would be the only advantage of such mega-speeds - most day to day tasks would be unaffected. If Youtube 1080p will work fine on 15Mbps, then you won't see the difference between 30Mbps single speed, 60Mbps double speed or 150Mbps on 3CA.
I must say though, when I once used my university's internet connection for uploads, they had a few computers on gigabit connections (I'm sure I got 600Mbps+ both ways) and the speed was phenomenal. A 2GB+ youtube video uploaded in a matter of seconds. It was crazy!

Only thing I could think where uplink CA would be useful right now would be for broadcast stuff where they're sending large video files from shoots back to the offices.”
50Mbps is fine for most uploads at the present day anyway, so I'm not too fussed about uplink CA. Chances are, in the future, there will be a time that uplink CA will become as important as downlink CA, especially in congested areas, but at the moment it's ok. I must pick up on what you said about the speed slowing down as the signal gets weaker - from my experience, anything below 1 bar can result in very low uplink speeds and even sometimes below 2 bars of signal, upload is significantly slower than if you had full signal.
