Did you manually build your splash recipe (bitbake psplash-myproject)?
This does not include it in an image yet. It must be added to image
features either manually or through a dependency. 
The psplash-raspberry package seems to be included in the dependencies
here
https://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/conf/machine/include/rpi-base.inc#n51 - maybe there is a chance to override this in your local.conf
The cleanest way might be to include this in an own machine definition
and override it afterwards.

There is a rather complex conglomerate of piped commands here, which
does this: https://community.freescale.com/docs/DOC-94953
