Fantastic photos Juli! I never even though about pre-bloom but I have had only a very few times in my garden. With the prebloom that first bloom of the season is always way out of wack, blooming way before the normal bloom time for the daylily.
The instant rebloom and instant rebloom with the fans coming up so close to each other they appear to be the same size (also called double scapes or double scaping) is what I am used to seeing around here.
