Low-E matchable coated articles, and methods

A heat treated coated article including a layer system supported by a substrate, the heat treated coated article comprising:

• a first dielectric layer on said substrate;
• an IR reflecting layer sandwiched between first and second barrier layers, each of said IR reflecting layer and said barrier layers overlying said first dielectric layer;
• a second dielectric layer overlying each of said first dielectric layer, said barrier layers and said IR reflecting layer;
• and
• wherein at least one of said barrier layers comprises a metal nitride that is nitrided to an extent so that the coated article has a ΔE* value (glass side) no greater than 2.6 after or due to heat treatment (HT).

A heat treated coated article including a layer system supported by a substrate, the heat treated coated article comprising:

• a first dielectric layer on said substrate;
• an IR reflecting layer sandwiched between and in contact with first and second metal inclusive layers, each of said IR reflecting layer and said metal inclusive layers overlying said first dielectric layer;
• a second dielectric layer overlying each of said first dielectric layer, said metal inclusive layers and said IR reflecting layer;
• and
• wherein at least one of said metal inclusive layers comprises a metal nitride that is no more than 75% nitrided so that the coated article has a ΔE* value (glass side) no greater than 3.5 after or due to heat treatment (HT).
