The object you have used as an example doesn't convince me. The reason is the edges that it has as a result, I don't know if the transparency of PNG is still inconsistent with those pixels that have antialising or is the image itself that has poor quality edges.
If it's the first, it would be a similar problem as using the defs with antialising and then seeing cyan dots in the final output of the def.
