The blue eyes are a form of pigmentation and since albinos have no pigmentation it can't be.
Double dilutes are caused by having two copies of a certain gene (cremello), therefore it's a trait. Albinism is caused by the body not producing pigment, therefore it's a disorder.

ALTHOUGH double dilutes can have the same problems with sun sensitivity that an albino would.

Research

If you own a Paint or are interested in Breeding
to Paint PLEASE Research first.

APHA.Com - Lethal Whites

Don't Believe It
Following are nine common myths regarding lethal white syndrome. The correct information is provided by the University of Minnesota Equine Genetics Group.
Myth #1: All overo horses are carriers of the lethal allele.
Fact: There are many overos that do not carry the lethal allele.
Myth #2: Twenty-five percent of foals from two overo parents will be lethal whites.
Fact: Because there are overos that do not carry the allele, the incidence of lethal white syndrome is less than 25 percent in overo-to-overo matings.
Myth #3: Registered tobianos, Solid-colored Horses, or Paint crosses cannot carry the lethal allele.
Fact: There are tobianos that have overo bloodlines, and these horses can be carriers of the lethal allele. Solid-colored Horses and Paint crosses can carry the lethal allele.
Myth #4: Totally white Paints are not carriers of the lethal allele.
Fact: These white horses are often carriers of the lethal allele.
Myth #5: All totally white foals born to two overo parents are lethal whites.
Fact: There are totally white Paints that are not affected by the lethal white syndrome.
Myth #6: Mares cannot produce lethal foals in consecutive years.
Fact: The genetic make-up of one foal does not affect subsequent births.
Myth #7: Only one parent determines if a foal will be a lethal white.
Fact: Both sire and dam contribute a copy of the lethal allele.
Myth #8: Crop-out Quarter Horses cannot carry the lethal allele.
Fact: A small number of crop-outs have been tested and found to be carriers of the lethal allele.
Myth #9: You can reliably tell the carrier status of a Paint by their color pattern.
Fact: This is false.

Fortunately in science, genetics included... all facts are falsifiable. :)
