Did you install the optional SGIRBG Pligin and code the SaveAs options correctly? I have never opened or saved an *.SGI file.
Optional Photoshop CC plug-ins
I thought saveoption.typename was read only you seem to set that to false? I would also think that the file extension would be something like .sgi not .rgb but then I have not installed the plug-in so I do not know the list of possible file extensions.
I just installed the Plug-IN I see .sgi is the default that .rgb is also valid and if you have both an Alpha Channel and a Spot Color channel you can only save and SGI file with an Alpha channel the Spot cant option is grayed out. If I delete the Alpha channel I still can not save an SGI with the spot color channel the alpha channel and spot color option are grayed out. If I have both a Alpha channel and spot channel I can saved a Layered PSD and a Layered TIF with both channels.
When I used the script you posted both .rgb file were saved no save as dialog opened. The night rgb file was smaller then the color rgb file neither had Alpha channels when I opened them. The save as changed your .rgb to .sgi. When I used save as to save a a .SGI when I opened that sgi file it had two alpha channels.

A few things I noticed;
In your samples, the PSD isn't saved yet. If I run the script with an unsaved PSD it errors out.
When I get the Save As dialog, Photoshop wants to save as a copy. Could this be why it's forcing the dialog? And if so any way to disable it?
My psd is saved for there would no blacking file no Path or Parent path if not save the script would fail with the document has not been saved.
saveOptions.typename is read only your set does not through an error and does not change the setting.
Photoshop is changing .rgb to .sgi I do not know why I would think it the Plug-in doing that. I do not see copy in either name I do see the .rgb is .sgi in the files saved.
My testing is on Windows 10 CC 2017. There are bugs in CC 2017 .....
