If I understand your query correctly, Fedora uses a Plymouth theme called bgrt
which displays the OEM logo and asks for the key in a nicer input. Try setting your Plymouth theme to bgrt
Thank you! I had no clue what to even search for but your comment pointed me in the right direction.
I spent the past hour setting this up and it almost works, but for some reason when I boot I only see something like “Loading initramfs” and then just a black screen and nothing happens. If I mash the escape key before I reach the black screen then plymouth works and I see the logo and LUKS password prompt.
Check out Archwiki plymouth , in the installation section, make sure that you have silent boot as that’s what usually blocks plymouth from displaying.
