Differentiation of console and GUI NeoVim

[ELLIOTTCABLE]

Hi!

This plugin is exactly what I was looking for (when I open nvim instead of vimr, my terminal-theme's background differs ever-so-slightly from my vim-theme's background, I want to prevent that); but the snippet from your readme looks like it'll cause the GUI NeoVim (VimR) to also have no background-colour:

" Default value: ['ctermbg']
let g:seiya_target_groups = has('nvim') ? ['guibg'] : ['ctermbg']

Is there a way to make this only apply to console-vim, even though it's affecting 'guibg'? (=
