Except for the orbit wobbles and the seasonal field tilt , the daily non linear relationship must the same as the difference between the solar day and a sidereal day, only a few minutes in time. Maybe you would not notice that but difference in curved path looks weird.
I turned on the ecliptic lines in Stellarium along with the equatorial . It is interesting to watch the centre of the ecliptic rotate around the CP as the time hour is advanced like two cages almost locked together.
