That depends a lot on art direction and stylization. Highly stylized games scale up to high resolutions shockingly well even with less detailed, lower resolution models and textures. Breath of the Wild is one good example that looks great by modern standards at high resolutions, and there’s many others that manage to look a lot less dated than they are with similarly cartoony styles.

If “realistic” graphics are the objective though, then yes, better displays pose serious problems. Personally I think it’s probably better to avoid art styles that age like milk, though, or to go for a pseudo-realistic direction that is reasonably true to life while mixing in just enough stylization to scale well and not look dated at record speeds. Japanese studios seem pretty good at this.
