I tried to rootcause my flicker over the last few days, it was definitely not due to the kernel and neither due to plymouth (tried by installing the respective packages from focal in eon and vice versa in focal). One thing I wanted to try next was initramfs but did not have the time to test.
Today I fully upgraded focal and the flicker is gone now :-).
