I realize that installation day pic was taken under possible, partial shade....but, does it look like a bright, sunny day, to you (in window reflection, etc)?
The weather, that day was mostly cloudy, with pretty good winds....yet...every clip I’ve seen shows everyone on what looks to be a bright sun/clear skies.
Just an interesting observation.

Yes, an observation of a strange picture. It does seem odd.
