This is not in a similar vein. Leading zero's for values less than 1 is the correct way to write values less than 1.
3-character or 6-character hex values is only a matter of optimization (fewer characters, which the compiler should be able to handle), and consistency (having both the 3- and 6-character versions in the same file or definition). Case is personal preference and nothing more.
