When new vehicles come with engine noise control, are they making engines quieter or louder? Is sports car engine rumble a lie, or are they blocking out some of that noise?

A lot of the “feel” of a powerful engine is because the engine is directly mounted to the chassis/frame of the vehicle. Some of this can be negated by placing buffers between the engine and the frame, so that the amount of vibration transferred to the frame is decreased. You can also have noise dampening material placed between the engine and the cabin of the car to decrease the amount of noise.
In higher end luxury cars, you have more of these dampening features because they also decrease the amount of road sounds in addition to the engine sounds. The size of the frame will determine how much of this dampening can exist. This is why even though the Cadillac CTS-V (third gen) and Corvette Z06 both use [6.2L LT4 supercharged V8](https://en.wikipedia.org/wiki/LS_based_GM_small-block_engine#LT4), they sound and feel completely differently.
