Yeah that is very disappointing as you lose a significant chunk of actual resolution due to that. It's like a third of your subpixels. It was one of the things I didn't like a about Quest 1 as you could see the SDE at the edges of objects, especially when watching movies, despite it having a reasonable resolution.
PSVR2 has a diffusion layer to make the SDE Less apparent, but that leads to a softer image overall.
Still it's swings and roundabouts as we used to say. Use OLED for HDR and vibrant colours, but get mura and smearing, SDE, and have to use Fresnel lenses, or use some form of LCD for a sharp display and the ability to use pancake lenses but suffer brightness and contrast issues, and washed out colours.
Though the Pro's QLED screens seem to be a reasonable compromise.
