"little fixed investment cost"

? I think you underestimate the costs for a company like Apple to go through the design, test, review, tweak cycle over and over again for each of those pixels. The cost to get it just right is not "little".

The extensive costs from the required multiple iterations required to arrive at such designs before they are seen by the public explains why companies like Samsung would prefer to save money, skip the iterations and simply jump straight to the end result by copying.
