    It's a ghost and his name is Casper :)
    I can see a face with eye, nose with nostril and a mouth. Now I've rotated it, I see it's two ghosts: one looking directly forward, and one higher up looking to the right.

    Or it's some strange posterisation artifact caused by a low bit rate source of whatever is out of focus behind her head.

    You have it in the whites too (bottom right hand corner) unless this is just the photo.
    May be your settings are making it worse, may be it's down to what you are watching, or a combination of the two.

    How often does it appear? and on what sources? Broadcast? or streamed catch up TV?

    Don’t worry it’s pretty normal I’ve seen it on 3 oleds now including mine as unfortunately they do show up poor source material but then so do top of the range lcd tvs but it’s worth it as 90% of the time the pictures gorgeous

    it generally seems to be down to low quality sources. If it's doing it on your bluray discs, I'd be worried. Sadly, even broadcast HD is a low quality source (relatively speaking, still better than SD).

    Where is the Channel 4 signal coming from? The TV's internal app/tuner or a separate device?

    Perhaps post your image settings.

    I had a Google of the manual and I can't find any mention of picture adjustments on the Panasonic unit bit if there are, try setting these to their default values.

    I've seen bizarre stuff like this when the source unit is adjusting brightness and contrast.

    I think it’s just posterisation from the relatively low bit rate on Freeview.

    I get this even on Blu-ray sometimes - only really notice on titles and intro logos - but not UHD disks. And not often on SkyQ, not sure if the box is doing something to convert reasonably well from 8 to 10bit colour.

    I think the Sony does the best job currently of smoothing these out (from what I’ve heard)

    The only thing on the Panasonic is on the HDMI connection as deep colour output and that has been on automatic since day one, the tv setting is as follows,
    Oled light-60, Contrast-85, Brightness-50, H+V Sharpness-10, Colour-50, Tint-0, Dynamic Contrast-OFF, Super Resolution-Low, Colour Gamut-Auto, Colour Filter-OFF, Gamma-2.2, Colour temp-Warm2, Method-20 Points Ire, Patten-Outer, Ire-100, Target Lum-130, Adjusting Lum-0, Red-0, Blue-0, Green-0, Colour-(Red-Sat-2-Tint-0-Lum-0) (Green-Sat-minus3-Tint-0-Lum-3) (Blue-Sat-0-Tint-0-Lum-0) (Cyan-Sat-0-Tint-0-Lum-2) (Magenta-Sat-0-Tint-0-Lum-0) (Yellow-Sat-0-Tint-Minus1-Lum-0), Saturation-0, Tint-1, Energy Saving -OFF, Eye Comfort Mode-OFF.

    If the set hasn't been professionally calibrsted, it might be worth removing all the colour management/white balance changes. Incorrect settings can yield odd results. Don't think you need super resolution either.

    Have you enabled deep colour on the TV?

    If the issue isn't manifesting in UHD blurays, it could just be your low bitrate sources.

    I have done a reset, the deep colour was off, where is best placed for it to be on, and will see what happens.

    Fairly confident there's no harm in leaving it on. Believe it's required for 10bit and over.

    Pause the TV on a tell tale scene and see if it makes a difference on or off.
