XnView Software

I'm confused.. I tried creating BMP screenshots from XnviewMP of JPG+PNG files with & without ICC and they're all different :\
The 2 ICC colors are more similar between them, but in theory the default JPG color should the right one

If I convert the JPG to PNG, the colors end up the same, instead.
There must be something different in the first PNG, despite Firefox displaying them identical.

EDIT:
I see that original has Adobe RGB, whilst the converted one has sRGB!
Maybe that's the reason, even if I dunno why I'm the only one seeing the difference (in XnviewMp).
