Not really. The perforations on the shadowmask (or aperture grille in later displays) were significantly smaller than the electron beam -- a single pixel would always consist of multiple phosphors of each color. There was never any expectation that pixels on the display would line up with the phosphors.
- tonyarkles 4y agoReading your comment and the parent comment sent me on a Wikipedia journey. I cannot believe that it wasn’t until today that I understood that the shadow mask/aperture grille worked by exploiting the different angle that each colour’s electron beam would hit the back of it. That’s wild and answers a question I didn’t even know I had, despite having lived a significant portion of my life with CRT displays.
