Samsung S23+ mmwave antenna

[IF57B]

Hi, have recently bought a Samsung S23+ US version SM-S916U1 which has a weird cut out below the power button. From what I ve read online this is a mmwave 5G antenna. Could only find a few posts on Reddit about it , I ll be using the phone in UK. Have tested the phone and it connects to 5G however I just want to make sure this a legit phone as I couldn't find any official info from Samsung.
