On the following tables you will see that hitting a KV1 tank form the top is worst than a JS2 or 3. It was always like that in game.
The plates thickness are in Meters.

You will see that the KV1 having a 35mm may become almost impossible to kill with a 37mm canon.

But the alleged difficulty to kill a IS tank with the 75mm, may be a tactics problem.
