I checked viewing raw images again.
There's a pitfall with Geeqie. If I select an ARW, but the folder
contains both, JPG and ARW with the same name, just with another suffix,
Geeqie opens the JPG, instead of the selected ARW.
After coping an ARW to /tmp and opening it from there, Geeqie seemingly
converted the raw file. The colours are equal to the colours of the
JPG, but the resolution is decreased to low quality.
Gwenview does the same, it converts to a sane colour profile, but it
cripples the resolution.
Digicam keeps the original resolution/size, but the colours are
disgusting.
nUFRaw keeps the original resolution/size too, but the colour profile
is completely off, too.
So far no viewer does view a raw that isn't completely broken.
Almost all JPGs are very close to what I've seen in reality, while the
ARWs are completely off, sometimes partly with a kind of
pseudo-solarized colour effect or if the colours are ok, the ARW images
are shrinked.
I don't expect that an ARW does look equal to it's JPG. I expect more
"depth"/"intensity", if the hardware is able to display it, or at least
something similar to a JPG, if the hardware doesn't provide the needed
quality.
The camera provides sRGB and AdobeRGB, selected is sRGB.
