When Saavik was recast in the movies, DC Comics kept their original Kirstie Alley-like character design for Saavik, but some later comics went for a more ambiguous look.
I read this, thought "This doesn't track with my memories," and went back and looked through the DC Comics from 1983 to 1986.
Before
Star Trek III, yes, DC's Saavik looked like Kirstie Alley. Tom Sutton wasn't particularly great at likenesses -- his interpretation of the characters at most
suggested the actors, though sometimes I think he was drawing William Talman (ie.,
Perry Mason's Hamilton Burger) for McCoy instead of Deforest Kelley -- but, for at least the first four issues, Sutton's Saavik was a pretty decent Alley. Eduardo Barreto did the "Origin of Saavik" story, and Barreto's Saavik also looked like Alley. Past
Star Trek III, I don't see any Alley in Sutton's Saavik. I don't see Robin Curtis
either, but this Saavik has Curtis' upswept eyebrows (which Alley did not). To me, Sutton captures the
idea of Curtis' Saavik, even if his illustration of the character doesn't much look like Curtis.
In the second DC series, the artists, including Gordon Purcell and Rod Whigham, who were much stronger at likenesses, drew Saavik as Curtis.
I have no idea who Adam Hughes' Saavik in
Debt of Honor resembles, as she doesn't look like either Alley or Curtis, though she has Curtis' upswept eyebrows.
Point is, I just don't see much, if anything, of Alley's Saavik in DC's comics post-
Star Trek III. Saavik may not necessarily look exactly like Robin Curtis in the comics, but she certainly suggests Curtis' look. (Note that I said DC. Marvel's mid-90s
Star Trek run featured Alley as Saavik; Patrick Zircher's Saavik in
Early Voyages was clearly Alley.)
