Description Cameron McCormack (:heycam) 2021-07-26 22:07:50 PDT
LayoutTestHelper only looks for profiles named "1", which is a default profile name.  Some devices have multiple profile names, such as my external monitor, which has this device info dictionary:

(lldb) po deviceInfo
    CustomProfiles =     {
        "HDMI HD" = "file:///System/Library/ColorSync/Profiles/sRGB%20Profile.icc";
    DeviceClass = mntr;
    DeviceDescription = "ASUS PB27U";
    DeviceHostScope = kCFPreferencesCurrentHost;
    DeviceID = "<CFUUID 0x6000037cc3e0> 4261DDFA-A1B4-1E80-AD62-026351A927F0";
    DeviceUserScope = kCFPreferencesAnyUser;
    FactoryProfiles =     {
        DeviceDefaultProfileID = "HDMI HD";
        "HDMI HD" =         {
            DeviceModeDescription = "HDMI HD";
            DeviceProfileURL = "file:///Library/ColorSync/Profiles/Displays/ASUS%20PB27U-4261DDFA-A1B4-1E80-AD62-026351A927F0.icc";
        "HDMI SD" =         {
            DeviceModeDescription = "HDMI SD";
            DeviceProfileURL = "file:///System/Library/CoreServices/Resources/Profiles/SD%20170M-A.icc";

We should look at the DeviceDefaultProfileID and use that as the profile name.

s/profile name/mode/, maybe.
