workaround костыль: Открыл в gimp /usr/share/themes/Calculate/splash-verbose.jpg. конвертнул его в 1024x768 и сохранил в ~/Картинки/verbose-1024x768.jpg. Потом запустил

jpegoptim --strip-all verbose-1024x768.jpg

и сохранил его в /etc/splash/calculate/images/verbose-1024x768.jpg.
Пересобрал initramfs:

dracut -fH --xz --kver=4.9.13-calculate --persistent-policy "by-label" --strip --prelink /boot/initramfs-4.9.13-calculate.img
