Bumping this thread. The issue is still present and severely limits usability of the lookdev mode. It is especially difficult to determine which direction is the main light source on the HDRI map coming from, and there’s constant general feeling of significant mismatch between lighting on the objects and environment background.
It’s quite inappropriate to simply blur all the HDRIs in the lookdev mode for completely arbitrary reason. There’s not proof it serves the lookdev purpose in any way.
