Detect shrunken text for block of type constant

Hey guys, Do you have an idea on how to detect programmatically in simulink if the text displayed on a constant block is shrinking or not? (See picture).

I'm looking for something like : >> get_param(gcb,'isShrink')

Thanks!

Do you mean detecting the case where the text label had to be changed to a different font size to fit into the space available on the block icon?

Yes, it is exactly what I'm looking for. Do you have a hint for me?

Thanks
