Bravia 8 OLED screen issue

[Austisi]

Hey everyone, hoping you can help/advise! Brought the Bravia 8 OLED (65") back in December so only a couple of months old, but today noticed weird 'jagged' lines all the way down the right side of the screen (pic included). It appears on every input (all HDMI inputs, PlayStation, Sky etc.) and if I use the Google TV options direct on the TV itself (Netlfix etc.) so definitely seems to be a screen error as opposed to an input one. It's barely noticeable during normal use, but when the image is static or in the options menu it's much more noticable.

It's probably been there the whole time we've had the TV, but just clocked it today when playing on the PS.

Decided to perform a panel refresh as thought it might be some sort of burn in, but it's made no difference. Any thoughts/help/guidance would be great. Wondering if it's just a normal thing or if the TV needs repairing/returning due to its young age - cheers!
