It's super early so this may end up phrased terribly or make little to no sense. I'm sorry. OTL I've also searched in an attempt to find a duplicate topic and had no luck but as I said. Pudding brain. Anyway.

In many cases of high white animals, the genes that cause the white spotting also cause one or more blue eyes. Something about lack of pigment translating to the eye as well. I think. In any case.

My suggestion is to, in certain piebald variations in which the white goes over the eye (such as broken or mosaic) have the white masked eye display as blue. This would not be genetically passable, purely aesthetic, as it would be linked to the piebald gene and therefore would not show in any non white spotted offspring.

I think it would be a fun touch of realism to my favorite mutation and maybe even add more value to piebald lions. Either way, it would be super cute.
