The complicating aspect of your illustration about Venus, is that it is much closer to the Sun than Earth is. We all know what happens to the soles of our feet when they are much closer to any campfire than our head (and brain??).
OTOH, it would be interesting to measure Venus and Earth surface temps if they were the same distance from the sun....
