Section background for modern pages finally rolls out to target release

I'm not sure either, and yet it is effecting my site design while using a classic theme. With the options for the classic themes there are a few that have a transparent overlay showing your image in the background, then the page sections are added on top. I attached some images of what our current theme is supposed to look like (nice lighthouse image in the background) vs. what it looks like now with the opaque section backgrounds spanning across the entire section to where you can no longer see the nice image, and the transparent b/g overlay feature is no longer visible... 

I actually found an example of what the home page used to look like prior to this change. This is from back in June so all the links are changed now, but you can see the way the background looks with the lighthouse image showing, this is using the "quick links" web parts, those have not changed their placement at all on the home page...
