Question How to see the difference in Delta E of two monitors with the naked eye?

I have two 4k monitors same brand, same model. The only difference is their Delta E as per their respective calibration sheet: one has Delta E 0.85, while the other one has Delta E 1.96

I have read technical articles stating that a monitor is fully "professional" when Delta E < 1 and in this case color accuracy, gamut and luminance have the lowest error rate.

But how can I see the difference practically? If I put my two monitors side by side, are there any specific programs, or images, or videos or games, or something specific I can use to see the difference between them?
I would like to be able to see the difference between them with the naked eye. Can you help me please?

Thank you in advance for your advice.
