The fact that piece!Erika sometimes seem aware of the meta world and of the meta knowledge cannot confirm she's always aware of what's going on there.
In that specifical istance is even more difficult as we don't know if Meta!Erika was present. She wasn't there when Meta!Battler witnessed the scene and, in the beginning, it was Bern that played with Lambda in the meta world and Bern likes to bully Erika.

Kanon and Shannon also have meta knowledge.
Piece!Battler has moments in which he seems to be connected to Meta!Battler following his directions and echoing his words as if the two were one and the same and moments in which he's completely disconnected by it.

So as far as I'm involved yours is just a theory with circumstancial evidence that clashes with circumstancial evidence she might not be aware of it.

From an objective point of view I'll say they both have a 50% possibility to be true or wrong and the sides of the scales are tipped merely due to our personal preferences.

Let's call it a draw...

Wait, can you tell me what are you talking about? Because I remember in the trial she had to prove all her red truths with human means...

Then I gave you evidence how it's possible piece!Erika worked in a certain way.

Well, maybe it's just a personal opinion but I deem pretty important the fact that Shannon and Kanon have exectly the same face. But yes, Ryukishi has a odd idea about what's important and what's not. Evidently realism isn't included in the important things... -_- ... though I seem to remember he also said Umineko is a logic game... and sometimes logic games can care less about realism...
