These are nice reviews,
But you might want to adjust the Einscan-S info, on the turntable you can’t scan higher then 17.5cm, and not the 20cm they advertise,
the width is also not 20cm, but I did not have time to exactly measure.
Also your test Auto-scan with the white sneaker you argue about it not filling certain top part in the final render, but you forgot that it is possible to put the object in another position, and do a “Continue scan”, and it will combine the two auto scans as one.
And I miss a little bit better explanation why glossy and matt parts, and also light and darker objects can have a different effect on the result.
Then they would know the difference between scanning mechanics.
