There are two types of Sierra "skins": Half Dome and Glacier Point.
If you would like to switch from one to the other, follow these steps:
Click on Admin at the top, and then on Settings:
From all the tabs at the top of the window, choose Display:
At the bottom of the Display window, choose the "skin" you want: (Glacier Point is the one most other libraries are using).
One you have chosen, make sure to click on Save Settings at the bottom of the window and OK:
You will then have to restart Sierra for the change to take effect. This will follow you no matter which computer you log into.
