You are correct:

  Show[
    GraphicsArray[   
      Partition[
        Graphics[{Hue[#], Rectangle[{0, 0},{1, 1}]}, 
          AspectRatio -> Automatic] & /@ Range[0, 0.9, 0.1], 3
      ]
    ]
  ];

works fine and, in this case, there are no intermediate graphics to 
suppress.

The documentation is slightly misleading. For example

  DisplayTogetherArray[
    {
     {Plot[Sin[x], {x, 0, 3}], Plot[Sin[x], {x, 0, 3}]}, 
     {Plot[Sin[x], {x, 0, 3}]}
    }
  ];

works fine. (Note that this would be different with Show and 
GraphicsArray). 

For the problem under consideration here, an Evaluate is required:

  DisplayTogetherArray[
    Evaluate[
      Partition[
        Graphics[{Hue[#],Rectangle[{0, 0}, {1, 1}]}, 
          AspectRatio -> Automatic] & /@ Range[0, 0.9, 0.1], 3
      ]
    ]
  ];

Cheers,
Paul
