After some investigation into this issue I have determined that this is down to the default WebGL mipmap LOD bias setting, which appears to not always give the best size mipmap at all levels. There is a very simple fix however.

Web7 apr 2024 · Mipmaps introduction. A mip or mip level is a version of a texture with a specific resolution. Mips exist in sets called mipmaps. Mipmaps contain progressively smaller and lower resolution versions of a single texture.
