Very similar, but not completely the same. Applying RPM doesn't affect operation, at least as far I understand the product. Boring the motor, or more precisely, leaving it unbored, would affect the operation. So from the standpoint of having an operating vehicle, there's a more compelling case to bore the motor than there is to apply RPM.
Ultimately, that small difference is rendered somewhat moot, as these are not vehicles that are meant to ever be operated again, at least on a frequent basis. So at that point, yes, a change is a change, regardless of whether it is visible. Visib;e changes are obviously easier to identify.
But I think the question you're really asking (correct me if you think I'm wrong) is "How should this affect OE judging standards?" That's a question for other people. It's just not how I think about cars. I follow this thread out of curiosity, and to learn things for which I might have limited, specific applications.
