Yes, this is exactly why many baristas will choose a darker or more full-bodied coffee for an espresso type drink vs a lighter roast for something like a pour over.

Darker roast coffees are also much more forgiving in general, since they already have some bitter taste to them in the first place.

It's still a better end product to brew the coffee or espresso well in the first place vs try to mask faults (bitterness, sourness, etc) after the fact.
