sparkling-featured-fullwidth not working

I am using the “full width” template choice, but I am not getting images set in functions:
add_image_size( ‘sparkling-featured-fullwidth’, 1140, 624, true );

how do I get the sparkling-featured-fullwidth size to kick in instead of the 750, 410 version?

Under customize - sparkling options - layout options: i have chosen “full width”.
Is that not enough? (individual pages should only need “default” to have full width kick in, but even choosing “full width” at the page level, I am still getting the 750px wide version.
