I also noticed that when I load the same scene in Vue 6 in wireframe mode, Vue reports 49% of resources available instead of dropping down to 10% immediately.

That could also point the finger towards something in openGL previews.
The same scene opened in Vue 5 Infinite gives me :

• 29% of available resources in OpenGL mode (instead of 10% in Vue6)
• 58% of available resources in Wireframe mode (instead of 49% in Vue 6)

I checked that issue with Instant / Background Draw sliders as well - they definitely are not behaving the same way they do in Vue 5.

Both issues have been reported officially.
