No currently it's not the case. Our education system is British and we are not called doctors unless we do PhD in this field.
Even in America you are not ENTITLED to be called doctors when you complete your 4years BS Optom, you have to do post degree fellowship of 3years to attain that label. You may say that American OD is equal to MPhil in optom.
