Is it correct to think that star eccentricity in PI is more discerning when using a small pixel camera?

(In other words, one might find that mount tracking is good, as judged by star eccentricity when using a larger pixel camera but find in star eccentricity is less good when using a small pixel camera)

Larger pixels usually lead to undersampling (with small-medium refractors) which "hide" tracking errors. Other way around with small pixels.

This was what I thought, thanks.
