large image size of 1440x1440 not pulling 2x of 2880x2880 image

I have updated the large image size to be 1440px by 1440px on Wordpress, however it only pulls 2048 for the 2x. I have created a 2x size of 2880x2880 and have also updated 2048 to be 2880x2880 however when I do it no longer shows the retina size.

Things I have checked so far: the image is being generated by Wordpress upon upload. I have taken the new large image limit put in place since 5.3 out using the specified filter. I have no lazyload plugins or other plugins that manipulate images apart from the plugin 'regenerate images'

this is all within the standard image block in Wordpress and Gutenberg

I'm at a loss at what else to do.

   // Image threshold removal
   add_filter( 'big_image_size_threshold', '__return_false' );


   /// UPDATE IMAGE SIZES

   //LARGE
   update_option( 'large_size_w', 1440 );
   update_option( 'large_size_h', 1440 );

   //MEDIUM LARGE
   update_option( 'medium_large_size_w', 1350 );
   update_option( 'medium_large_size_h', 1350 );

   //MEDIUM
   update_option('medium_size_w', 675);
   update_option('medium_size_h', 675);

   //THUMBNAIL
   update_option('thumbnail_size_w', 320);
   update_option('thumbnail_size_h', 320);

   //2048x2048 
   add_image_size( '2048x2048', 2880, 2880);
