BTW, tooltip says "Use the current world background to light the preview render" but it doesn't seem to work? I have a green World color but the preview looks the same. preview_material_world.blend Is this a bug?
Please report this as a different issue. it is perhaps that EEVEE does not support this, then we need to remove the button, or that eevee should support this and then we need to enable the background during rendering. I think that the
Preview World
button should be removed. Cycles seems to work as expected.Reported here: #66699
