>"It's scaled properly.">shown that it isn't>"It's still bigger than the player."That's moving the goalpost. It is either properly scaled, or it is not. The original question was "Does it shrink?" in regards to catching the Wailord in OP's image and have it following you. The answer to that is either "yes" or "no".
And the answer is "yes", the large Pokemon DO shrink when following you after being caught.
