I use Redshift, and while I do notice the change (so it’d be impossible for me to tell how much of the insomnia-preventing effect is due to placebo), it doesn’t bother me at all.
(Edit: BTW, with Redshift the transition is gradual throughout the day, rather than near-instantaneous at sunset and sunrise.)

f.lux offers fast (20 seconds) and slow (60 minutes) transitions.
