That holds true as far as the *software* is concerned, not the hardware. And that's usually reserved for the "K5" notation. "Touch" should pretty much always mean a venerable original Kindle Touch

.
Which is why I tend to use "FW 5.x" to make that SW/HW difference more explicit nowadays.
TL;DR: Nothing we can do about a KV, short of opening it up, sorry :/.
