ayu theme colors on Neovim or Vim look dim

Hello everyone. I really like this theme. But when I use it on neovim or vim (In terminal) under xterm or st. The colors don't even look as close as the ones on the screenshots provided by the author of this theme. I have set termguicolors Why do my colors look dimmed, not as bright as the ones provided in the screenshots?

No, I actually gave up on this them. The colors dont even look the same on neovim TUI. I think this theme is designed for a GUI version.

I'm using neovim and the theme looks great, do you have a screenshot for a better understanding on how it looks like?
