"Pre-cooked" RAW?
Certain manufacturers embed a small part of the processing directly in the sensor, which means that some degree of processing occurs before the RAW image is sent to the RAW converter. In this case, measurements for these "pre-cooked" RAW images can be biased by this processing.
To avoid any potential impact on our measurements, DxOMark always tests all cameras to detect any pre-processing of RAW images. A processed or pre-cooked RAW image has different characteristics from a genuinely unprocessed image. To some extent, these characteristics enable us to walk back the processing and reconstruct the original image to perform unbiased measurements, and we always inform the user about models with embedded pre-processing
