Webform Status in Webform Submission Twig Template
Indeed, calling {{ webform }} inside webform-submission-information.html.twig only contains a link. But since you have the webform_submission you can get the webform and from there can call isOpen and isClosed.
&lt;div class=&quot;current-webform-status&quot;&gt;
  &lt;b&gt;{{ 'Current Webform status'|t }}:&lt;/b&gt; {{ (webform_submission.getWebform.isOpen) ? 'Open'|t : 'Closed'|t }}
&lt;/div&gt;

or
&lt;div class=&quot;current-webform-status&quot;&gt;
  &lt;b&gt;{{ 'Current Webform status'|t }}:&lt;/b&gt;
  {% if webform_submission.getWebform.isOpen %}
    {{ 'Open'|t }}
  {% else %}
    {{ 'Closed'|t }}
  {% endif %}
&lt;/div&gt;
