As per comments I understand, that you want to return a true Observable, if the response.checkData value is included in the pageUid array.

You can do the following:

  this.data.getresponse().pipe(
    map(response => pageUid.includes(response.checkData)),
  ).subscribe(checkResult => console.log(checkResult));
