Different logo with transparent header

Hello,

I want a different logo on a page and all portfolio items.

I get to work with the normal header but if transparency is on it works for the sticky header when you scroll but not for the transparent header see: https://www.zinkwaliteitsborging.nl/cursus/kwaliteitsborging-bouwplantoetsing-3/

code i used:

add_filter('avf_logo','av_change_logo_img');
function av_change_logo_img($img)
{
    if( is_page('1005973') )
    {
        $img = "https://www.zinkwaliteitsborging.nl/wp-content/uploads/2023/01/Academy-logo.svg";
    }
    if(is_singular('portfolio'))
    {
        $img = "https://www.zinkwaliteitsborging.nl/wp-content/uploads/2023/01/Academy-logo.png";
    }
    return $img; 
}
