it’s also a typical panasonic issue.
there shadows/near blacks have more magenta then it should be.
it’s off balance.
i had the same issue in night shots.
The darker spots got some magenta casting which i couldn’t repair. (G80)
i think your OOC jpegs are fine. (panasonic has long exposure correction which eliminates the redischnes.
DxOPL Staff did some readjusting of the Camera depending data.
Edit test with FastRawViewer and PL:
before g80 correction and after.
edit 2: see your rawfile exposure data:
it seems you could raise exposure to +.75 as in 3/4 of a stop.
(not that this help you for this image but you could use exposure bracketing for this kind of high dynamic scenery’s and find out in post which is best for development.)
