We discuss that the nature of projective measurements in quantum mechanics can lead to a nontrivial bias in non-Markovianity measures, quantifying the flow of information between a system and its environment. Consequently, in the current form, envisioned applications are fundamentally limited. In our trapped-ion system, we precisely quantify such bias and perform local quantum probing to demonstrate corresponding limitations. The combination of extended measures and our scalable experimental approach can provide a versatile reference, relevant for understanding more complex systems.
