Frankly that is a laughable statement, as Samsung Android devices are anything but smooth given their TouchWIZ-based bloat.
The Xperia Z3 is supposed to be using Triluminous technology that includes quantum dots. That will probably have to be confirmed once the phones are released, since in the past there have been Triluminous phones without incorporating quantum dots, but the possibility exists.
While there are some things I like about AMOLED, unless you have content optimized for it, it's very battery inefficient. And the most popular smartphone applications are generally things like Facebook, web browsing, and a few other things that still don't offer a "dark" mode optimized for AMOLED, that minimizes the number of lit background pixels. White backgrounds are not a friend of AMOLED. .
1) Your statement is laughable, as it's clear I was talking about the display's motion clarity.
2) None of the Xperia devices use quantom dot filters, and neither does the Z3 or Z3C. Triluminos is just a brand name.
