Hello dear, Rogério Vairo. All templates build by community members. And some templates was imported from partners via referral system.

Yes, there is, and it really looks cool. To do this, try putting your iPhone in dark mode.

This is not a pure UI/UX design, it’s just a mockup, they are used for presentations and the better the mocap is made, the more interesting it looks in the presentation

Usually, these mockups designers are used to create presentations for the client. To show how the client’s images will look in the layout of Instagram.

Make mockups by yourself is a long time, so designers use such ready-made solutions, they look very realistic.

Biggest Instagram mockup dark mode what I ever found. Fully vector icons, all layouts made by symbols. Easy to change the color scheme.
