Question is not does, but percentage

That is true, but in a rather useless way.

I have read quite a bit of "this sensor still gathers full color info".

But I probably miss one thing. Let's clarify that.

Yes, the sensor gathers full color info.

But does it RESTORE full color info? If it doesn't, then there's no advantage in gathering it.

That is an excellent question, but just a little off...

I don't think it likely it can fully restore colors in all case.  BUT, because the top layer changes with wavelength changes that affect the lower layers, I think you can restore a very high percentage of the colors successfully with careful processing.

For example, you have four jewels, each of them is either black or white. They are ordered in a random 2x2 block. You throw them one by one into a box. So that means you gathered the full color info - because none of the jewels were lost.

Now if someone tries to extract those jewels from the box and put them back into 2x2 block, he will never know in what order they were thrown or what place they should take. So the info cannot be restored.

But that's not what is happening here.  The top layer is locking is position of those jewels as they are added.

Now imagine shooting a completely red target which doesn't have blue in it. Will the blue layer record zeroes thus giving no spatial info?

Here's the other key.  That is not a "blue" layer, and it will not be recording zeros.  It's a top layer, and it should be recording low values even for red input.
