Temperable three layer antirefrlective coating, coated article including temperable three layer antirefrlective coating, and/or method of making the same

A method of making a coated article, the method comprising:

• providing a glass substrate;
• disposing a silicon-inclusive medium index layer, directly or indirectly, on a first major surface of the substrate;
• disposing a high index layer over and contacting the medium index layer, the high index layer having a thickness of at least 85 nm;
• and
• disposing a low index layer over and contacting the high index layer,
• wherein the coated article is heat treatable so as to have a ΔE* value of less than 3.

A coated article comprising an antireflective coating supported by a first major surface of a substrate, wherein the antireflective coating comprises, in order moving away from the substrate:

• a silicon-inclusive medium index layer disposed, directly or indirectly, on the first major surface of the substrate;
• a high index layer disposed over and contacting the medium index layer, the high index layer having a thickness of at least 85 nm;
• and
• a low index layer disposed over and contacting the high index layer;
• wherein the coated article is heat treatable so as to have a ΔE* value of less than 3
