Well, that's the hardware capabilities of the CPE, but as you say the network itself has to be physically wired to support it... and that's not a small task.
The maximum hardware capabilities haven't ever been particularly relevant to the actual marketed end-user speeds. After all, previous (DOCSIS 1.0, DOCSIS 2.0, and debatably the VMNG300 D3.0) hardware have all been capable of much better ratios than current CPEs that actual products never came close to offering.

Sightly better on Euro networks but even on the best of those the ratio is 60MHz, of which perhaps 45MHz is usable, to 256MHz via modern 32 channel CPE out of, again, over 900MHz.

And if a highly capable D3.1 CPE were to be deployed on the current networks within the next year or so, it would actually make it worse, not better, since the CPE would allow more downstream to be utilised yet the upstream spectrum would still be limited by the physical network.
