It all comes down to phenotypes. If there are three possible phenotypes then it's Codominant.
ie Motley:
Normal = both genes normal
Heterozygous or Motley = one motley gene, one normal gene
Homosygous or Motley-purple patternless = two motley genes
If there are only two then it's Dominant.
ie Salmon:
Normal = both genes normal
Salmon = at least one Salmon gene, could have both genes Salmon
The difference is if you have a pile of babies from a pairing where each parent had a Salmon gene, you cannot reliably sort the babies into het for Salmon and Homozygous for Salmon. Yes, several of the babies can be visually identified as probably het or probably Homozygous but there is too much of a grey area in the middle where the babies are not easily identified. And the probables are just that, not like a motley pairing where duh, that has to be homozygous and duh, that's a het.
Super is a slang term used to describe a snake with a homozygous gene pair. Typically used for Dominant genes where the hets and homozygous animals cennot be reliably sorted.
ie Super Salmon would have two Salmon genes.
