I can't tell from your comment if this is called from multiple threads. If so, I
don't think CR_DEFINE_STATIC_LOCAL is thread safe. If not, can you add DCHECKs
that its called on the right thread?

It seems that src/ui is not allowed to depend on src/content. The IPC code
upstream ensures we run on the FILE thread on Windows and the IO thread on all
other platforms.

+  static bool initialized = false;
+
+  profile->clear();
+  if (!initialized) {
+    initialized = true;
+    ReadColorProfile(&screen_profile);
+  }
+
+  profile->assign(screen_profile.begin(), screen_profile.end());
+}
+
+}  // namespace gfx
