I've dumped everything with Polydumper.

The manuf is the same as the one on CR4/HW-W.

Polydumper is able to :

dump the Boot1 set as the default boot image (whether it's inside the ASIC or in an external Flash-NOR)
dump the ASIC internal Boot1 image

So it can return up to 2 different Boot1 images.

On HW-W, both Boot1 images were different.
On HW-Y, both Boot1 images are identical.
Since there is no Flash-NOR anymore according to Adriweb, then it implies the calculator is booting on the ASIC internal Boot1 image - thus it's the same image which is dumped twice.
And of course, it's the new 4.0.1 Boot1, hence the new ASIC.

I've just managed to get the CR6 bootlog :

It seems to confirm most of our discoveries :
