Raspberry Pi OS • CM4 how to boot silent and show a custom splash screen

I would like to suppress the boot messages and display a custom splash screen.

I followed some hints on the internet and tried the following.
To /boot/cmdline.txt I added the parameter:

• quiet
  splash
  logo.nologo
  plymouth.ignore-serial-consoles
  loglevel=0

I also changed console=tty1 to console=tty3
My complete /boot/cmdline.txt looks like this:To change the default splash screen, I replaced the file:
/usr/share/plymouth/themes/pix/splash.png
with my own image.

The outcome is a bit weird.
On reboot mostly the custom splash image is shown but it gets scrolled up and out of view because there are still some messages displayed (I think these are systemd messages)
Sometimes neither the splash image nor any messages are displayed on reboot (blank screen)

I also tried to add
system.show_status=no
the the commandline to suppress the systemd messages but to no effect.

What have I done wrong here? I would be thankfull for any hint.

Some information about my system:PS: this is my first posting on this forum, so please excuse any errors in formatting etc. and don't hesitate to correct me.
