Hmm, if the color profile applied by the system itself is somehow 
causing GIMP's screen color picker to pick the wrong color, this doesn't 
seem irrelevant, but rather indicates a color management problem somewhere.

In GIMP, in the Color Management section of Preferences, I'm guessing 
you have color management enabled, yes?

In GIMP Color Management Preferences, what monitor profile did you 
select? Is the box to try to use the system monitor profile checked or 
unchecked? Also, is the box to use black point compensation checked or 
unchecked?

Also which version of GIMP are you using?

Do you know what monitor profile is chosen by the system "(Ubuntu -> 
Settings -> Devices -> Color)"? Is this the same monitor profile that 
you selected in GIMP in the Color Management section of Preferences?

If you are happy with results of simply disabling the color profile 
applied by the system, and don't want to dig any deeper, please ignore 
this email! I'm curious as to what went awry, but sometimes these things 
can be difficult to track down.

Best,
Elle
