Yes, that's the only advantage of using directly the Swing and AWT canvases within Java3D, the HiDPI works as expected simply by taking to account the scaled size which is exactly what Ian does in his fix :)

The only remaining stuff to fix is the part depending on NEWT used in Java3D 1.7.0, Canvas3D and JCanvas3D should work as expected.
