Simulink background color via CLI

i know that in order to change simulink bakcground you right click > Canvas > choose a color

i also know that you can set vis CLI the background (and foreground) of block, for example:

set_param(blockPath,'backgroundcolor',Color); 

but this doesn't work for a block_diagram, as it lacks the background or foreground property.

Is there a way to replicate the query shown in the image above via CLI?

Most probably i just cannot find the correct property name, but i've taken a look several times at the whole documentation and found nothing. Also i tried to see if i could find something, but with no luck :

get_param(modelName,'ObjectParameters')

after going through basically every property of the model with:

get_param(modelName,'ObjectParameters')

i found that the background property is named ScreenColor, so to set it:

set_param(modelName,'ScreenColor',rgbTriplet)

Note: i will not delete the question since it may help someone in the future.
