The clue is in the name "All" pass.
Of itself the allpass filter doesn't create a
change in the frequency spectrum.
You might want to consider why an analog phaser
has up to 12 stages of allpass filtering.
Indeed, the amount of delay introduced by a single
allpass filter isn't enough to produce a
"delay based effect"....but stack then up in series
and the delay becomes significant.
Hope that brings something worthwhile to the discussion,
apologies for bandwidth if not.
