Why have i worst results in Optimization ViewModes with the low poly model? (Low vs High poly model)

I made a low poly version in Blender of a previus model i generated using geometry script (10000 vs 400 triangles).

I seem to have worse results with the LowPoly model in some cases.
It even seems that some Optimization ViewModes do not work at all with the low poly model.

Is it normal or is something broken?

Obviously both models are using the same materials (instances of this material for all colors)

I found the problem.
The problem was Nanite support enabled.

I unchecked it an now both models has the same permomance in the optimization view modes.

Well, seems i can not measure de difference of performance between Low and High poly using the optimization view modes. But also seems nanite does not help with low poly models.

Would it be worth using the 10,000 triangle model with nanite?

Thank you so much!!
