Answer 1

Option 1 :You can attach a JSLink to your fields and in that javascript you can write js code to call your user profile service based on Modified by column and populate into a custom DIV.

Below are few code samples available using JSLink

Option 2 :SPFx extension field Customizer

With JSLink i have done a similar code where we need to query User profile service when user enter the username and populate other data in columns. so it was achievable.

Answer 2

We can use User Profile REST API with jQuery to achieve it. The following code for your reference, add the code into a script editor web part in the display form page.

<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
    var displayName=$("table.ms-formtoolbar td.ms-descriptiontext:contains('Last modified at')").find("a.ms-peopleux-userdisplink").text();

    var accountName=GetAccountName(displayName);    
    var requestUri = _spPageContextInfo.webAbsoluteUrl +
                  "/_api/SP.UserProfiles.PeopleManager/GetPropertiesFor(accountName=@v)?@v='"+accountName+"'";

    //execute AJAX request
    $.ajax({
        url: requestUri,
        type: "GET",
        headers: { "ACCEPT": "application/json;odata=verbose" },
        async: false,
        success: function (data) {
            var userProperties=data.d.UserProfileProperties.results;
            var htmlTable='<table width="100%" border="0" cellspacing="0" cellpadding="2">';
            $.each(userProperties,function(i,property){
                htmlTable+="<tr><td>"+property.Key+"</td><td>"+property.Value+"</td></tr>";
            });
            htmlTable+="</table>";
            $("table.ms-formtoolbar").after(htmlTable);
        },
        error: function () {
            //alert("Failed to get details");                
        }
    });
});

function GetAccountName(displayName){
    var accountName="";
    var requestUri = _spPageContextInfo.webAbsoluteUrl +
                  "/_api/web/siteusers?$select=LoginName&$filter=Title eq '"+displayName+"'";

    //execute AJAX request
    $.ajax({
        url: requestUri,
        type: "GET",
        headers: { "ACCEPT": "application/json;odata=verbose" },
        async: false,
        success: function (data) {
            if(data.d.results.length>0){
                accountName=data.d.results[0].LoginName.replace("#","%23"); 
            }

        },
        error: function () {
            //alert("Failed to get details");                
        }
    });
    return accountName;
}
</script>
