Thank you jp!
This appears to not actually be true and reveals (I think) an inconsistency in
the KiCad code.
PCB_DRAW_PANEL_GAL::SyncLayersVisibility
is VERY different from
PCB_EDIT_FRAME::syncLayerVisibilities
PCB_DRAW_PANEL_GAL::SLV modifies the visibility of the layers themselves,
taking care of behind the scenes after the visiblity on the layer is changed.
PCB_EDIT_FRAME::sLV seems to only update the checkboxes based on what is
retured from IsLayerVisible().
My current problem I think is solved by PCB_DRAW_PANEL_GAL::SLV, while another
problem I have worked around is solved by PCB_EDIT_FRAME:sLV.
See workaround for checkboxes

Function SyncLayersVisibility Updates "visibility" property of each layer of a
given BOARD.
which includes:m_view->SetLayerVisible( i, aBoard->IsLayerVisible(
PCB_LAYER_ID( i ) ) );
which is defined as: { 389 wxASSERT( aLayer < (int)
m_layers.size() ); 390 391 if( m_layers[aLayer].visible != aVisible
) 392 { 393 // Target has to be redrawn after changing
its visibility 394 MarkTargetDirty( m_layers[aLayer].target );
395 m_layers[aLayer].visible = aVisible; 396 } 397 }
While PCB_EDIT_FRAMEsyncRenderStates () to update checkboxes from
"IsElementVisible"syncLayerVisibilities () to update checkboxes from
"IsLayerVisible"
Function syncLayerWidgetLayer updates the currently layer "selection" within
the PCB_LAYER_WIDGET

You could need to call:
ReFillLayerWidget();
ReCreateLayerBox();
syncLayerVisibilities();
syncLayerWidgetLayer();
syncRenderStates();
All are methods of the board editor (PCB_EDIT_FRAME) not the PCB_DRAW_PANEL_GAL.
