Planes are definitely being retrieved rather than tiles:

https://github.com/ome/omero-fpbioimage/blob/master/omero_fpbioimage/views.py#L74

omero=> select sizex, sizey, sizez, sizet, sizec from pixels where image = 881;
 sizex | sizey | sizez | sizet | sizec
-------+-------+-------+-------+-------
 49101 | 53202 |     1 |     1 |     3
