That Hoover Dam scene has at least two types of lights in it - with very different colour temperatures.
It's an example of a subject that has strong, unnatural colours - and lots of them.
So Ektar did what it was supposed to do - render the scene with strong, unnatural colours.
Your scene also has strong colours in it - albeit natural ones - and your Ektar also did what it is supposed to do.
By the way, you do understand, don't you, that there is no such thing as automatically correct colour in any print - whether done optically or from a scan?
All the automation does is essentially guess at what the colour is supposed to be, and print to that guess. The guess is based on a lot of built in experience, but in the end it is still a guess.
The same applies to custom manual prints, except that there the guessing is done by a human, not a machine.
I used to work as a colour printer, doing mainly optical machine prints for professional photographers. We would first do a test, then correct for a final print based on that test. Even then, my decisions on colour and exposure were based on what were essentially educated guesses about how the subject appeared in real life. Some of that guessing was quite reliable, because skin tones were often the most important element, but even then we would sometimes be tripped up by different complexions and racial and sociological factors.
