No, this is a somewhat different feature,

Indeed `corfu` provides a completion UI, but not an inline completion preview.
`corfu`'s completion UI replaces the *Completions* buffer for
in-buffer completions.  Completion preview is something related but
independent from the completion UI.  Namely a suggestion for a single
completion candidate that automatically shows up after point as you
type.  It appears inline, as if you've already inserted that candidate,
in that sense it gives you a preview for the completion operation.

The package `corfu-candidate-overlay` is another project that does
provide completion preview and builds on top of `corfu` instead of
`completion-at-point` directly.
