STM32L073/Unique device ID registers/unique ID bits [95:64]

I am confused by the naming "unique ID bits" which implies that these bits are really unique from device to device.

Are these bits really unique from device to device, or are the other bits (WaferNr,LotNr [0:63]) also required to build a unique id?

The whole 96 bits are unique. Byte/halfwards and words from that 96-bit number may be the same on different devices.
