How do I modify the result? Having an issue with HOOK_views_pre_render and HOOK_views_post_render, trying to alter the rendered output of the view. There are similar questions like: Hide view results with hook but I am not seeing the results as I am expecting under $view['result'] 

There is what looks like a full entity and not the markup that I'm expecting.
You can use HOOK_views_post_execute() and cycle through the results rows,  updating the row with something like:

        foreach ($viewExecutable-&gt;result as $key =&gt; $rr) {
          $title = $rr-&gt;_entity-&gt;getTitle();
          // update $title value...
          $viewExecutable-&gt;result[$key]-&gt;_entity-&gt;set('title', [['value' =&gt; $title]]);
        }
