The logo call 

PREFIX schema: <http://schema.org/>
SELECT DISTINCT ?graph ?type ?resource ?logo
WHERE {
  VALUES ?resource {
    <http://www.bco-dmo.org/affiliation/191>
  }
  VALUES ?type {
    schema:Organization
    schema:Dataset
  }
  GRAPH ?graph {
    ?resource rdf:type ?type .
    OPTIONAL { ?resource schema:logo [ schema:url ?logo ] }

  }
}
ORDER BY ?graph ?type ?resource ?logo

works, but when I use a dataset URI 

PREFIX schema: <http://schema.org/>
SELECT DISTINCT ?graph ?type ?resource ?logo
WHERE {
  VALUES ?resource {
    <https://www.bco-dmo.org/dataset/646128>
  }
  VALUES ?type {
    schema:Organization
    schema:Dataset
  }
  GRAPH ?graph {
    ?resource rdf:type ?type .
    OPTIONAL { ?resource schema:logo [ schema:url ?logo ] }

  }
}
ORDER BY ?graph ?type ?resource ?logo

The logo field is blank.
