This is a user forum, you are not addressing apple here  just  fellow users

 best you can try is to have them replace the screen

iPhone Screen Repair & Replacement - Official Apple Support

so it's a matter of the price vs. the bothering level

you can try contacting apple Support ->  Get Support (apple.com)

and or give them feedback -> Product Feedback - Apple

putting a screen protector on it can make it less visible
