STM32L433RCT6 package marking - 'Z' by the ARM logo ?

[DevinZhao]

I would like to ask if there has been any change in the screen printing of STM32L433RCT6 from Taiwan, as the Z next to the ARM in the first line is not close, while the Z next to the ARM in China is close. As shown in the following figure.

Please don't double post. You can edit your post if you need to correct or add information.

The two chips clearly were not written with the same process. The font is also quite different. With them being made at different locations, I'm not surprised.
