New GTS ST Question -- do these rear window defroster lines seem normal?

[Bigal1267]

Picked up my GTS ST this past Friday and it’s my first Porsche! So far bc waiting on PPF, only driven 20 miles.

I saw the rear window defroster lines (not sure what’s the correct term), does it seem normal or not?. I see some defrost line darker and some lighter. Not even in my Model X I see the difference in the lines. So is it normal or something not right?

Not noticed on mine. Some of the elements could be the PCM antennae rather than the heated rear window elements.
