I guess night mode works by applying a colour profile in much the same
way as any other colour profile. So night mode would continue to
experience similar problems even without a custom profile installed.
Night mode IS a colour profile so it may well hit the same bug.
I now think we should be focusing on fixing the affected apps, maybe
just one or two broken libraries. In the meantime, keep in mind
disabling colour profiles is a good workaround.
** Summary changed:
- Ubuntu default colour profile distorts colours on some machines (white looks
green, too dark, or under-saturated)
+ Chrome/Chromium and Image Viewer distort colours if a colour profile is
enabled.
** Also affects: eog (Ubuntu)
Importance: Undecided
Status: New
** Also affects: chromium-browser (Ubuntu)

Bug description:
Using Ubuntu 18.04.1 LTS
Running on an i7-6700k with a GTX 1080
Reproducible with nvidia-driver-396 or xserver-xorg-video-nouveau
and a single 4K screen (TV) connected via HDMI.
The issue:
Any dark content displayed by an effected application (e.g. a very dark image
or dark themed web page) is much darker than intended making it almost
unusable.
This only effects applications that are launched when the 4K screen is
connected. If i disconnect the 4K screen, launch the app via a
different 1080p monitor then reconnect the 4K screen the app remains
unaffected.
The only apps i have found so far that are effected by this are Google
Chrome and Image Viewer. That said this is only noticeable when the
app is displaying dark contend so if other apps are affected it may be
impossible to tell.
The attached screenshot uses a black to white gradient image to clearly
demonstrate the issue.
Is seems like it may be an issue with colour depth as bellow a certain
brightness it just goes strait to black.
