Colormoved: why are whitespaces sometimes flagged as "added" and not "moved" ?

• My issue:

I think we can kind of agree that aesthetics wise, if we conceive of this picture has having 3 "blocks" they look like this:
(this formatted block is probably only understandable on dekstop)

                                                     1: UGLY
                                                     # has a weird mix of green and blue

2: UGLY
# has a weird mix of purple and red

                                                     3: LOOKS GOOD
                                                     # clean separation between blue and green              

Basically, it looks bad because the "moved" backgrounds (blue and purle in my case) are interrupted and return to the generic red/green "for some reason". And it feels pretty hard for me to actually understand what that "some reason" is 😅. There are no actualy whitespaces on the lines after the code moved, I'm just using that name cause I coulnd't think of another way to describe it. The lines seem to fail to be recognized as "fully moved lines" in BLOCK 1 and 2 but not 3 ?

Is there anything that delta accepts as a setting that would make BLOCK 1 and 2 look like 3 ? with a continuous background color ?
