#144 – tried and worked, so thanks to said user for providing a method.
Funny thing is, that the one I downloaded a couple of hours before High Sierra was released in the MAS, and the one just now from the CLI tool have slightly differing file sizes:
GUI MAS: 5,028,626,
858
CLI MAS: 5,028,626,
885
Both have creation date of "Friday, 14 July 2017 at 21:58" though, so likely irrelevant.
BTW, just as in the standard MAS GUI version, it will not find Sierra on the MAS using any CLI search commands, e.g.
mas search "macOS Sierra" only displays the result
1246284741 macOS High Sierra

While this is a great get-around for those inclined to use it, it's still needless obfuscation by Apple for the average joe user, isn't it. And the zero Apple explanation is worse.
I may be wrong here, but one could guess they've not provided Sierra installer in the MAS GUI directly, because presumably one cannot run Sierra or older macOS on the new APFS?
So unless the user is knowledgeable enough to
reformat their machine before then doing a
clean install of any pre-High Sierra OS, they'd run into error messages. And this is not the type of thing Apple want the average joe user to have to deal with, as it'd be a bad user experience and thus make Apple look bad.
Complete guess work of course, as we have no idea on any of this, and Apple are being overly coy about it.
