Is it possible to import the demo theme?

Hello.
I want to import the demo theme as seen on https://demo.themegrill.com/estore/
I downloaded and installed the eStore theme in my WooCommerce shop, but it looks so bland and empty it doesn’t even look like what I thought it was
I understand I need more content, but on my Customize theme option, I can barely change color of stuff

Alternatively I could change some colors with css but I’m not that expert at it and I would like my theme to look like what I saw on https://demo.themegrill.com/estore/

How can I do it? Is it possible to import that so I can just change as my needs?

Thanks in advance ??
