It's black border around a super bright picture, that has to my eyes the same effect - it's like kind of ghosting overlay.

Actually I'm even more disgusted by the PDAF wiring stripping in the Sony (potentionally Nikon Z, too) mirrorless:

This is something than cannot be easily fixed in the postprocess, at least with ACR I'm using. True, this stripping may not be encountered frequently but there is relatively high probability of its occurence if you use some kind of backlight. Which is not a rare case among portrait photographers. I do think this is a kind of serious issue because photography IS about light, isn' t it?

And the banding in pulled shadow just spoils the great dynamic range you can work with. 

@Brightcolors:   "I prefer not pulling shadows many stops, I find pulling shadows many stops a very odd fad."  - why do you say that? I think when used creatively, it can save you the weight of external lights! When I'm at home, I will attach you some pics with heavily pulled shadows that wouldn' t be possible with limited dynamic range. And I'm simply so happy I do not have to work with flashes so often... 

This may be a reflection effect from the sensor to/from to the protection glass.
Sensors are darn shiny things and if you throw too much light on them, there can be freak effects I reckon.

By the way, if I observe the PD AF banding in an image shot by someone else, it is a 1st hand observation (me doing the observation).
Like in this DPReview image:

The EOS R will not have this banding, as Canon does not  use a similar PD AF implementation. So no need to wait for that.

And Nikon's compressed (lossless) RAW does not have issues, just like Canon's CR2 format is compressed without issues. It is Sony's compressed format that is problematic. The Sony A7R III gives 82mb per image uncompressed.

I prefer not pulling shadows many stops, I find pulling shadows many stops a very odd fad.

The only thing that I see there is a completely useless shot.
