> Does this have any unwanted side effects?

The only known side effect is that on some systems, the boot animation
and final login screen will disagree about the correct display scale and
change size.

> Can I combine this again with quiet splash without any issue?

Yes "quiet splash" should be present and should never be removed.

Title:
  Disk unlock prompt is never displayed. Screen stays black.

Status in plymouth package in Ubuntu:
  New

Bug description:
  Unfortunately the screen stays black before password prompt shows up. 
  This happens since I've migrated from 22.04 to 24.04. 
  Even a fresh install shows the same symptoms.

  What helps is to detach the HDMI cable, attach it again and the TV
  shows the password prompt for luks.

  I did not try yet the removal of "splash" in the parameters. As this
  was indicated by others who faced the same issue.
