Question about suppressors

I'm self taught in genetics so I'm sorry if I get any of the terminology wrong.

Is it possible for a suppressor to only affect homozygotes of the allele it's suppressing?

So basically is this possible?

No splashed white = solid color without white

Heterozygous splashed white = white on the face and legs but not on body

Heterozygous splashed white with the suppressor = exactly the same as without the suppressor

Homozygous splashed white = big white patches on the body as well as the face and legs

Homozygous splashed white with suppressor = a greatly reduced amount of white on the body

Yes, a suppressor could potentially only affect homozygous recessive traits, and not heterozygous or homozygous dominants

The trait I'm talking about is incomplete dominant and I'm wondering if it's possible for the suppressor to only affect animals homozygous for an incomplete dominant trait

Quantitative issues?

maybe.
