Horizontal Bar across top of Screen

Slightly odd issue, switched from my ps5 over to Netflix and there's a tinted bar across the top. I turned it off and on again, switched inputs, apps, let the screensaver come on, no dice. What's going on here? No it's not burn in.

Anyone else come across this?
