Note that only the red channel appears to be unscaled.

There's definitely scaling on the red at some ISOs. Take a look at

in the 1/250 FPN tests
114A8184.CR3 ISO 125
114A8187.CR3 ISO 250

But yes, the blue and greens are more consistently scaled than others.

You seeing how Canon routines does intermediate ISO settings by scaling.
An exception being the 5DS/5DSR models.
