Is this humbucker out of phase with itself?

[Herbie]

I have a 1984 Gibson ES-175. It has the Shaw humbuckers and I play usually only the neck pickup, which I like a lot.

Sometimes I wonder the thin sound of the bridge pickup. Could the coils in it be in out of phase?

Or do all the ES-175 bridge pickups sound as thin as this?

The pickups are about as close to the strings:

That sounds normal to me. It's common for the bridge pickup to be thinner/quieter than the neck pickup, all else equal. That's why it has also become common for people to use hotter pickups in the bridge position and/or set the two pickups at different heights.
