WordPress image quality is really bad

Hey!

For example: when i upload a 4339x6129px resolution image after the upload its only 1812x2560px resolution and when i’m attach this image to a post to a featured image the image will be more worse than 1812x2560px it is only 560×430 or 800×430 but some images will keep the original good quality even if the image is only 800×430 or 560×430, what’s wrong?

I was tried to add these codes seperately to functions.php but nothing changes:

add_filter(‘jpeg_quality’, function($arg){return 85;});
add_filter( ‘jpeg_quality’, create_function( ”, ‘return 80;’ ) );

And i disabled any kind of caching or CDN but nothing.

Thanks
