Is the lens profile info dependent on focal length? My guess is yes. So what if in that case the lens reports the incorrect focal length and as such the wrong correction curve is applied?

I can’t imagine the “corrections” being applied to be appropriate for any lens. Something is either very corrupted in the firmware data to begin with, or there is glitch in translating the metadata into actual image correction.
