I don't know how Samsung's NFC implementation works, but the only correct way to use NFC or Bluetooth Low Energy is to exchange a session key, and then use WiFi for the actual data transfer. NFC and Bluetooth LE have way too low a data rate to be useful for anything else. (Well, I guess it's OK for syncing my step count from my FitBit.)

Actually, this makes me wonder why anyone bothered with NFC or Bluetooth LE for file transfer, etc., when WiFi Direct is just as good.

In android, only things like links or contacts are sent directly through NFC. For large files, it uses bluetooth or WiFi direct. The use case is really good though, if you want to transfer a file, you just hold up your phone, touch the screen, and away it goes. All the bluetooth and WiFi setup steps are hidden (but to be honest, bluetooth in android is a bit dodgy. You can't even send arbitrary files without special programs).

Can't Bluetooth LE "upgrade" the connection to full speed?

Also, since I'm asking: Does anyone know if my Bluetooth-LE-supporting HTC One will consume very little battery if Bluetooth is turned on? I have an inkling that it will need to keep advertising Bluetooth proper, so it will use as much battery as Bluetooth always has.

No. Bluetooth and Bluetooth LE are distinct, incompatible protocols.

That's sort of what it does. NFC is the initiator, Bluetooth is the transfer protocol. It's in the AOSP code and is straight forward.
