These are two ways of expressing the same information [1]. Whether a character appears in an XML document literally or as a character reference, this shouldn't matter to most applications. They'll receive the same character code from the parser.

When adding text programmatically to a DOM, the text is not processed as if it were being read by a parser. It is added as-is to the content. So if you create a text node with the value "&#10;" you're literally adding "&#10;" to the content not code point 10.
