You can convert a DTB blob back into source code:

dtc -I dtb -O dts -o devicetree.dts blob.dtb

Big, biiig, biiiiig difference!

PS: You can also examine it directly as a directory tree in /sys/firmware/devicetree/*

You can convert ACPI bytecode back to source with iasl. No difference at all.

Then you can load them in u-boot and there's no need for any ohter blob.

Yes, and you can do this with ACPI as well. There's no difference between the inherent freedom of ACPI and Devicetree.
