I noted this on the King's Quest wiki, that a few sources actually call it "King's Quest I: VGA".
See for example the King's Quest Collection Series Manual.
http://www.sierrahelp.com/Documents/Manuals/Kings_Quest_-_Collection_Series_-_Manual.pdf Although technically its not VGA, despite marketing.
However, just because the King's Quest Companion or Collections calls it a 'VGA version" doesn't mean that they are correct. The Collection's also states, that it has icons like KQ5. But that's of course also 'wrong'.
Also you can find a number of Sierra sources that do infact call KQ1 remake "EGA".
KQ1 SCI actually had more in common with King's Quest 4 SCI, or Quest for Glory II's version of the Sci engine (which although VGA compatible were only utilizing EGA graphics).
On a related note, early on many Sierra games were released in both VGA and EGA versions. For example King's Quest V came in two versions. Although later on they included multiple versions in one box, and you just changed the graphics settings via the installation software.
