Not my experience unfortunately.
The crud and spit comes back past the case as it unlocks/extracts and into the receiver that way. Higher pressures for longer in the barrel mean as soon as the case no longer seals there's another path of least resistance the gas takes. The receiver ends up dirtier than unsupressed Direct Impingement. This experience from using an Adams Arms (AA) piston in a suppressed .223.
The AA also has only two functional settings; full open and half closed. Half closed is what is used for normal unsupressed. Although to be fair it doesn't feel like the action is being belted around when suppressed.
