I set my .screenrc and .bashrc files to the following answer here: Strange behavior of vim color inside screen with 256 colors
But the colorschemes still do not work correctly in GNU Screen. If I'm out of GNU Screen the colorschemes are perfect, just in Screen.
Any other advice in fixing this issue would be appreciated!
Here are my bashrc, vimrc and screenrc files...

* EDIT: Okay, I did something to the vimrc file (I had the 'set background=dark' commented out :/ ) That fixed the syntax highlighting.
But now terminal's background color bleeds into Vim’s. Here is a screenshot of the two: https://s24.postimg.org/i81kjz1cl/Screenshot_from_2017-06-04_18_47_55.png
This is what the colorscheme should look like in gnu screen instead: https://s7.postimg.org/47fo5qd97/image.png
*Solution: I found that the following code needed to be added to my .vimrc file. This fixed the background issue. I was led to the solution from this URL, https://stackoverflow.com/a/15279464/8110853 comment. Breifly, it looks like the t_ut option in Vim only "uses the current background color" if the value is a non-empty string, which it is in xterm-256color but not under screen-256color. The solution is therefore to "clear Vim’s t_ut value if Vim happens to be running inside any 256-color terminal". The following codes, placed inside .vimrc does this. I put it at the end of the end of file.
if &term =~ '256color'
" disable Background Color Erase (BCE) so that color schemes
" render properly when inside 256-color GNU screen.
set t_ut=
endif
