I guess I can see what you mean. Maybe it was that late 70s make-up style.
I have had several wonderful meetings with Grace Lee Whitney, both at conventions and 1:1 interview style. She told of her great excitement of being invited back for ST:TMP (and "Phase II" before that), and then her utter dismay when the Makeup Department sent her out for her first in-character photo shoots in front of director Robert Wise. He took one look at her "beauty makeup" that had been applied and said,
"I don't want Kirk's geisha girl in this movie". Grace was sent back to have her makeup
removed.
Majel and Nichelle were allowed to have some beauty makeup and Persis Khambatta's contract actually allowed her to send out all of her Ilia stills to a photo studio so they could be airbrushed, but Janice Rand's character in the movie was seen as "a mechanic", hence the overalls jumpsuit version of the uniform and no beauty makeup.
She was invited back for ST III
- after principal photography had been completed - by Leonard Nimoy himself. Grace's scene was shot at ILM and her "look" in that movie was essentially her "look" in real life at the time. Just after ST II's release (again devastated that no one had asked her to play Rand in that one, even though Chapel and Rand are both in the ST II novelization), she visited our Australian convention - looking
amazing in beauty makeup, a shirt skirt and white cowboy boots - and decided, at the banquet, to go teetotal. Her experience with Aussie fans had been so positive she decided to kick her old habits.
Here's a photo I took of Grace departing Sydney airport for home, after attending that Brisbane ST convention and seeing a local ST II premiere (1982) with Aussie fans:

She also looked just as stunning at DeForest Kelley's star ceremony on the Walk of Fame, just after ST VI, and she made a point of chatting to almost everyone in the crowd.
