I took some (poor) edge shots of 1/8" & 1/4" Baltic birch and 1/4" box store underlayment. Notice the 1/4" BB has 5 layers where the 1/4" underlayment has 3.
Decent writeup here- https://kingsfinewoodworking.com/blogs/news/baltic-birch-plywood-what-is-it-why-is-it-better#:~:text=It also has more dimensional,likely to shrink or expand.

Sorry, was referring to this:
ALL BALTIC birch ply is made with exterior glue.
Do you have any source specifying exterior glue on the baltic birch?
