Okay further investigation has shown a gain when the canvas is very large (eg.
1000x1000), but also when scaled in css, eg.
<canvas width="1000" height="1000" style="width:500px; height: 500px"
></canvas>

there is a substantial benefit *provided* the painting is spread out
suffuciently or over a compact enough region to prevent repaint rect coalescing
from effectively repainting the entire canvas
