As from Vue 8 the indirect skylighting (skydome lighting gain) takes much more effect. Try playing with this.
Also for outdoor/landscape scenery you should take into account the "optimize for outdoor rendering" radiosity option, if you haven't already.

And more: The render settings differ. A Vue 7 scene imported to Vue 8 with "Preview" render settings will switch to "User settings".
I know this is about Vue 9, but when you come from Vue 6, a lot of things will have changed, like in the examples above.
