As far as I have learned to understand the notion of the -originally Japanese- word "bokeh" (pronounced in two equally stressed syllables with the "bo-" as in "bottom" and the "-ke" as in "Kenneth"), it is the aesthetic amount of blur in the out of focus background.
So I understand things like this: bokeh is very subjective. Some may find a blurred background very pleasing that is soooo blurred, it leaves nothing there to recognise. Some may find a blurred background pleasing that still gives you an IDEA of what there is in the background, though it must yet be so out of focus that it does not disturb the in-focus motif.
All you photography specialists, to whom I do not belong: am I right?
