Can confirm that's the case.
When using (f.e.?) plymouth, the gpu drivers and corresponding firmware
gets added to initramfs. If you then have much more and much larger firmware 
files (nvidia f.e. added 2 fw files of 23 and 38 MB respectively ...) then you 
get a corresponding much larger initramfs.
If you add a (fixed) bug in initramfs-tools where symlinks to directories 
weren't preserved, but full copies were made, you could end up with a single 
initramfs of 240MB ...
