Hi,

thank you, but it's a misunderstanding. 
You might have noticed that I'm migrating from Gimp to Krita ;), so I'm
not clueless regarding lossy formats.

I've never seen a difference regarding colour (saturation) like this
before. Issues related to loss are a very complex topic, see
https://stackoverflow.com/questions/384991/what-is-the-best-image-downscaling-algorithm-quality-wise/6171860.
A photo loaded already comes by a format... anyway, it's off-topic to
describe the whole process. It's not that easy as you said. However,
Krita provides several display options for scaling, but at 100% no
scaling is involved at all. If you take a look at the screenshot, the
view of Krita does show the picture creating the impression of a
saturated, yellow biased picture, while the exported JPEG, the
wallpaper, creates the impression of washed-out colours.

A countercheck, loading the _same_ JPEG of an original photo with Krita
and Mirage, both at 100% / 1:1 shows such a difference in
colouration, too.

FWIW the wallpaper is set via feh.

Apart from the scale settings, Krita provides settings for colour, too.
The default sRGB-elle-V2-srgbtrc.icc is used. I didn't test all
available (it's time consuming, since changing takes a while of
processing), but non of those I tested were better.

It doesn't make a difference if "Use system monitor profile" is or
isn't checked.

In sum, my question is really related to a Krita issue.

Ralf
