Being able to pick iOS7 wallpapers in iPhone X with iOS11

Hi everyone. I couldn't find this question posted, so I apologize if I'm asking something that has been already asked in the past 🙂

I have a 64GB iPhone X with iOS11.4.1 . When I got it, I restored it from my iCloud back from my old SE and that phone was also backed up from my old 4S. I do have the teal/purple dynamic wallpaper that iOS7 offered still (see here: http://prntscr.com/kaitch). I was wondering if there's a way to get it back if I pick another one, I see the new dynamic wallpapers do not include the one I have, and I really like that one.

Thank you!
