Someone who actually studies this stuff can maybe correct me but I think this adds only a single bit of entropy (multiplies the possible combinations by 2) and thus is almost negligible.

Nope, it's one bit extra entropy per character. The attacker must try all possible capitilazations of each word (horse, Horse, hOrse, HOrse, etc).

You've doubled the character set so it's not negligable.
