Your AJAX call should auto-detect a JSON response, but it won't hurt to explicitly tell jQuery about it:

$.ajax({
    type: "GET",
    url: $SCRIPT_ROOT + "_status",
    dataType: 'json',
    success: function(data) {
        $('#Result').text(data);
    }
);

The contentType parameter is only used for a POST request, telling the server what type of data you sent.

The data object contains whatever your Flask jsonify() response returned; in this case it'll be a JavaScript Object with the BoilerRoom, etc. keys.

Since you are loading JSON over a GET request, you may as well use the jQuery.getJSON() method here:

$.getJSON(
    $SCRIPT_ROOT + "_status",
    function(data) {
        $('#Result').text(data);
    }
);

This does exactly the same as the $.ajax() call but you get to omit the type and dataType parameters, and the url and success parameters are just positional elements.
