I think it would, the boot logo screen is where you select the palette for monochrome GB games on a real GBC/GBA. The GameBoy logo changes colors to preview which of the 12 palettes you are selecting, then boots the game when you release the d-pad.
The palette feature aside, I agree it's nice to have the original boot screen in an emulator, helps add the feelings of authenticity and nostalgic experience.
You can see the difference it makes when you use the official bios with other emulators like ReGBA and PSX4all.
