You can use this suggestion to set a default background color for the web page.

Using the above suggestion, and code from here (with some slight modifications):

from selenium import webdriver

driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')
driver.set_window_size(1920, 1080)

driver.execute_script("""(function() {
    var style = document.createElement('style'), text = document.createTextNode('body { background: #fff }');
    style.setAttribute('type', 'text/css');
    document.head.insertBefore(style, document.head.firstChild);

I was able to take a screenshot with white as the default background:
