Since Snapdragon 8 Elite (gen 4), a change in Chromatix caused seemingly most devices to render shadows with much lower precision than predecessors, at least when NOISE_REDUCTION_MODE and EDGE_MODE are set to off. In the past, you could usually count for these two CaptureRequest keys to allow you to get a photo mostly resembling a RAW. Now, the difference between jpegs and raws is impossible to not notice.
There are workarounds (RAW-based JPEGs, possibly a vendor key), but this is going to be your experience with Lineage's camera app (Aperture) and on many others for the foreseeable future on the chips in question.
