It's my understanding that bokeh refers only to the quality of OOF blur, not the quantity. Therefore it can be better or worse, but 'more bokeh' is an non sequitur.
"non sequitur" is not a noun; it is a verb (in the negative).
"sequitur" is the 3rd person singular of the deponent Latin verb "sequi" ("to follow").
So "Non sequitur" means "It does not follow".
So you don't precede the phrase with a definite, or indefinite article.
