I don’t think so i’m afraid. , maybe someone else might know a work around. the 3D viewports run in lower res and colour depth i imagine to keep them more responsive.
In the blender preferences there are options for viewport multi sampling and texture limits and anisotropic settings, you might get a more acceptable display if you change some of them. i cant guarantee anything i suggest you experiment with each of those settings and see if the change is favorable.
Sometimes you just gotta poke buttons to see whats what.
