The fact is, you don't know what errors you have or don't have because you don't have a meter. Nobody can help you with this question because your perceptions of what you are seeing are very likely to be inaccurate because human vision is EASILY fooled.. Even if you know every way that human vision can be fooled, you cannot compensate for it or make it look accurate.
And there is NO way to "hide" errors. Leaving worse errors at the dark end of the luminance scale risks having every star field in every movie looking green or red or some other color. That' VERY obvious and VERY annoying, so you cannot say you are better off with larger errors at the dark end of the luminance range. Anything you see at high luminance ranges is HIGHLY susceptible to human vision errors and what you are CERTAIN is a yellow error could easily be caused by too much blue at higher or lower steps. But you'll never see the blue error unless it is very severe. Instead, you see a yellow error... though if you have a large visible blue error, adjacent steps are highly likely to look yellow even if they are "perfect".
