Nikkor 20mm f2.8 D. The image I took the grabs from had not been processed by me, although as you say it will have had the preliminary Lightroom initial import process.
I haven't turned it off, it's not usually a problem. If it's CA then I haven't seen black or dark grey CA before.
I don't think that is CA. That would show up more around the branches to the right of the frame. It's more like a sharpening or compression artefact or a sort of edge confusion.
I don't suppose it's high ISO noise reduction ?
