Galaxy A55 rainbow effect on screen

[Members_jTxN477]

Guys I just bought a Galaxy A55. My last phone was a S9+. Im pretty happy about the phone. The only issue I have is that when I tilt the screen I have like a rainbowish effect especially on a white background . I dont have another cam than the one on my phone so I cant take picture but I've found one that is exactly similar to  my problem:

That's something I didn't have on my S9+. Is it normal ? Is it because it's a midrange phone and not a flagship one ?

Thanks for your help !

Unfortunately I have the same issue on my Galaxy a56. I am so surprised because I had done a thorough research before buying this phone and almost nobody had ever mentioned such a problem nowhere. It's so annoying and distracting when reading stuff. If it really is a built-in issue then why no one has ever mentioned it!
