Everything is clear to me; I'm glad that the light has been shed on these game versions. Thank you, Lance, I've learned a lot thanks to you.
You were also right about the KQ1 game by einstein95; it was a misunderstanding. Indeed, the detection table of ScummVM indicates that the version of his game dates back to 1986:

Maybe it is also necessary to correct on Agi Wiki and Sierra Wiki that KQ2 1.0W and 1.1H are not PC DOS games, but only bootable versions. The same applies to versions 1.1J, 1.1K, and 1.1M of The Black Cauldron.
And a huge thank you to them
