No, the level of benefits and the tier needed depends on each airline. It's not standardized like in Oneworld

For example if you are Platinum you are going to get Priority Boarding with Qatar at DOH and GRU but with Iberia you are not going to get Priority Boarding even if you are Black Signature. Likewise, if you are Platinum you can use any Qantas lounge but when you are flying with Iberia you can only use the lounge at MAD

You need to look at each airline in the link I provided
