Thank you for writing in, are you referring to this page? If so, regretfully this page is not part of the Demo, that is our sales page.
The closest Demo to that and has the same vibe is the Ethos Demo 3.
Setup - Demo Content
Keep in mind that Standard Demo will only import place-holder images for you to replace.
That banner area is a Slider (Revolution Slider) and sliders are not part of the standard demos.
That layout which the logo and menu are in the bottom is a setting you need to do on the Slider itself. (refer here)
Regretfully, we can not provide you the Slider itself, however, you can always follow the guide that I provided here on how to set up one.
You can install the Revolution Slider under X > Validation > Extensions.
Hope it helps,
