I do not know if this is to help.

As you say you can get the current scrollHeight, what is happen if you place a anchor on bottom of the page? and use a script as

var curr = document.body.scrollHeight;
document.location.href = "#bottompage";
if(curr == document.body.scrollHeight) {
  alert("Bottom of page");
}
