Is the efficiency of a DC DC converter Load independent? (www.meanwell.com)

I'm currently looking into various DC DC converters and was confused that the Meanwell DDR-60 series only shows a typical rating but says nothing about the efficiency at idle. From AC/DC converters I'm used to have a curve that starts at idle and maybe 70% and goes to 100% load, having the peak at ninetee something.

They might be willing to spec it as "quiescent current" (current drawn at 0 load) even if they don't provide a full curve. Annoying that it's not on the datasheet.
