Anyone knows how to manually tweak the dimming of an ambiance?

Personally I really hate it and don't like it. Only the lockscreen show my background as it should be, but since that screen is pretty useless as it is I never get to see my background bright in my Jolla.

I digged around but the best information about ambiances I found were:

https://together.jolla.com/question/...wto-ambiences/

But neither of these talks anything about how to tone down the darkening of the picture ones you scroll down.

Anyone, or is it only me who is hating this feature? BTW I think that this even got more aggressive with the latest update
