Problem with camera target texture and replacement shader

I'll explain my setup using this image:

C2 is my main camera which renders things normally, no scripts attached

C1 is the second camera, which has a replacement shader and outputs to custom target buffers so I can use them in the replacing shaders.

Q1 is a quad that shows the depth buffer from C1

Q2 is a quad that shows the color buffer from C1

Object A has it's shader replaced with a shader that only outputs (0, 1, 0, 1)

Object B (the sphere) has it's shader replaced with a shader that outputs (C1-depthBuffer, 0, 0, 1). As you can see in the "Camera Preview" screen.

Why doesn't the color buffer from Q2 (in the game view) looks the same as the Camera preview? And how can I make it look the same? The difference in the camera preview / game view that I'm talking about is that on the camera preview you can see the depth of object A, but in the game view, you can't.
