the image used to render _quickly_ thumbnails in digiKam is a small jpeg
image embeded in RAW and taken by camera during shot. It's not a full image
resolution version, it's a reduced one generally used to render preview in
TV or camera screen.

This JPEG image use all camera algorithms to render properlly color/gamma.
It's not the RAW image. In fact it have the same render than if you take a
real JPEG image instead a RAW.

But you cannot compare RAW image data and JPEG image data : RAW do not have
color space, JPEG is always in RGB color space.
