Fram uses thicker steel here:

This is a "fact."

I think that was me, I’m still not convinced of the measurements and the tread got so derailed I never did any further checking. It may indeed be thicker (an oft repeated “fact”
or it may not be.
I also never made an in-depth post about the obvious differences in the media.
I’m just so sick of the silliness around here I checked out on both issues.
OP, I agree giving the Ultra a second chance would be prudent.
I thought your measurements seemed pretty close, because the Fram number was about the same as I got. Pretty strong correlation. I measured Toyota filters .016" or so, taken from memory like the Fram number I gave. Toyota Denso Japan about .020" thick. Don't know about other OE filters yet.
Fram uses thicker steel here than their standard filters, doesn't say how much:

Here is a picture and explanation from Fram's website. No doubt a stronger can material will stress the seam less.
