No. The dots on the screen obviously have an effect (you can't have a red dot where there is a blue phosphor), but you need not have even illumination from a dot. And, in a three-CRT projector, there are neither dots on the screen nor shadow masks (or aperture grilles).

An analog display will spread the energy over a broader area, but
the peak will be narrower, and it will be brighter (or darker,

occur ANYWHERE in the analog line.  Digital pixels can occur only
where their grid allows them to occur.

But I thought that this theoretical difference disappeared because
analog displays now use shadow masks?
