The last time i've seen a 24-bit color desktop mode was in the VLB days, so...

I am playing some games that provide option for 16/24/32 bit colors. For all purposes, 16/32 bit colors just work fine but 24-bit colors, it just crashes the game. Is 24-bit color really unsupported? Isn't there any alternative ddraw.dll that supports it?

This might do it.

DdrawOverrideBitMode

This overrides the default bit mode. This requires either Dd7to9 or EnableDdrawWrapper option to be enabled.

EDIT : Then again, what would be the point ?
Unless you had a game that supported 24-bit but not 32-bit, of course.

I checked it's constituent wrappers but none of them seem to support 24-bit colors, the option is grayed out. I managed to gain 24-bit option access in this game with DxWnd but it just crashes. The only game that worked in 24-bit color, needing DxWnd was Icewind Dale 2

I second that.

Personally, I've seen it in the Windows 98SE days last time, I think.
But with Windows 95 era hardware. A Pentium 75 with integrated 2D graphics chip, I think.
Something like Cirrus or S3, maybe. Which was used in both VLB and PCI designs.

Edit: Now that I think of it, maybe some PC emulators/virtualizers had a 24-Bit limit, too.

I went to test Icewind Dale 2 on 16, 24, 32 bit colors. At first, I could see a clear difference in 16 and 24-bit colors, but when I compared 24 and 32-bit colors, they both looked completely same. So the game setting to use 24-bit color is setting 32-bit color in effect? I attached the photos of test, note that the sizes of the 24-bit and 32-bit files are quite same as well:
