I do not see a question here, so just a general remark.
Sony ARW 2.3 (lossy compressed) format is:
- 11-bit values (11 bit base + 7 bit deltas)
- expanded by expansion curve w/ ~0..16383 range (really slightly more)
dcraw converts it to ~0...4095 range, this is OK for old cameras but not for A7 series. LibRaw uses 'natural' camera range.
