I don't really understand what you are asking. tmux has no control over what goes into the terminal scrollback and when, nor does screen, it's entirely up to the terminal.
If I run screen with altscreen off it leaves the terminal scrollback unaltered, same as tmux w/o smcup in terminfo. What do you think they are doing differently?
