I just tried that using my launch day 16 Pro Max. Mine shows blue splotches on the exposure at ISO 6400 at 30”. But as soon as I launch it into Lightroom, all that blue disappears with no editing yet & is no longer present. So for me, this amp glow from the sensor doesn’t really matter.

This is not a super valid test. In fact even without lightroom, if you edit your "raw / dng" photo in IOS photos app, it will become super dark immediately.
What happens is that your raw photo is still recording the blue / purple hazy signals, they are very low in amplitude in raw, and in jpeg preview (such as what you see in iOS Photos before you go to edit mode) those values are automatically amplified to a gain that shows the blue and purple to be visible.
What does it mean in practice -
1. Assuming you have a different unit that is unaffected - Then the raw sensor readings are going to be so low or approaching zero that no amount of automatic gain will result in blue / purple whatever, it will stay pure black. That is in essence what we hope for is an accurate representation of the scene.
2. If your unit is affected, and you take a picture of a really dark scene, not like a complete dark one, but a very dark one. The automatic jpeg processing WILL give you blue and purple haze along with other signals from objects that produce or reflect light - your subjects. Depending on the gain necessary but out of your hands.
Even if you go to raw and edit yourself, you will find that you can make it dark enough to not see the blue / purple but it will not match the brightness necessary to compete with the JPEG processing....
2.1 In IOS 18 to 18.1 the camera likes to use ISO 10000 and above and this issue is very very obvious and very blue.
2.2 In IOS 18.2 onwards the camera SW tries to use ISO 5000, or lower like 2500 etc in very dark scenes and you may avoid the issue.
TLDR, raw just underexposed the bad image.
