I am just curious, because currently Windows does really weird and I wonder if HDR would be beneficial with the current options available.
I also wonder what 32 bit post processing effect means.

No, HDR was never thought about or possible during the GC/Wii. 32-bit PPE is unrelated.

You are confusing "32-bit colour" with "32 bits per channel'. ...which is very easy to do admittedly. 32 bit color is just 8 bits per channel times each channel in RGBA - R8+G8+B8+A8 = 32. The GameCube uses "24 bit colour", which is 6 bits per channel RGBA. HDR10, on the other hand, has 10 bits per channel RGBWA.

I wrote about this whole confusion and why these standards occurred this way here - https://forums.dolphin-emu.org/Thread-feature-request-hdr-support?pid=470425#pid470425

You are right, but since sometimes Alpha doesn't count, hdr is sometimes done as R10+G10+B10+A2, so since the other feature was called 24-bit, I expected this actual functionality to be also called 24-bit.
But wait what, 6 bits RGBA? I wouldn't expect the alpha to be included in that.
Let this be a lesson to every last one who didn't knew!
