It does but I think you need Gen 2. Most have Gen 1 which is same speed as USB 3.0.
Of course, real-world transfer speeds are limited by source and target storage devices. Only way you’d actually see anywhere near close to top speed is when doing large file SSD to SSD transfers with UASP support.
The Kindle’s storage maxes out at around 10-12 MB/s, iirc. That’s for block level reads with Win32 Disk Imager. Writing small ebooks is slower.
Apart from being reversible, pretty much the only benefit of USB-C in the case of e-readers is if you have other devices (e.g. smartphones, etc) with USB-C and you don’t want to carry multiple cables.
The batteries on e-ink readers are small enough that even 5V/1A (e.g. PW4) charges pretty fast. The PW3 actually charges at just 5V/0.5A. USB-PD fast charging levels would likely just generate excessive heat and kill the battery more quickly.
