Check menu Settings / Configure digiKam / Album view. I assume that in
your case the item in Misc Options "Embedded preview loads full-sized
images" is unchecked (therefore the preview is based on JPEG embeded in
rw2 and digiKam does not do any conversion).

digiKam uses a different tools to convert from raw to JPEG than the
camera manufacturer. Therefore, the result does differ.
Depending on what is the resolution and quality of the JPEG embedded in
raw file, you may want to extract it  and compare side by side with
digiKam's output. However, if you consistently find the embedded JPEG
better, then shooting in raw may not be your target...
$ exiv2 extract -ep1 image.rw2
where -ep1 is the first thumbnail embedded in the raw file (some raw
formats have more thumbnails).
