A
number of studies have used quantum
dots to produce the
similar effects but because the
dots are much larger and not uniform in size, due to the nature
of their synthesis, the results have not been reproducible — not every device made with quantum
dots behaved the same way.
That said, other Alexa - powered devices, like the Echo
Dot and the Amazon Tap, haven't seen
similar discounts, which suggests that Amazon is only trying to shift large
numbers of the model which is to be replaced.
