Large firmware take longer to read from disk, must be fully decompressed and dearchived because cpio. And it's possible that the initramfs remains resident in memory indefinitely - I don't know whether it's garbage collected or when or how. Is it subject to eviction by swap? No idea. We should find out.
The initramfs ist the "real" os booting. It chroots into the mounted "/" you know, but it's still there. When you shutdown, the sysroot "/" is unmounted and a few other ressources are given free. Now, the initramfs is gone from memory, which does not matter anymore ;)
So, yes, you waste 250MB+ of Ram for it, if you boot the rescue system.If the firmwareblobs were parked on /boot, as i suggested, it would just be a symlink and would not take significant orders of memory.
