According to one or more embodiments described herein, a coated article may comprise a transparent substrate and an optical coating. The transparent substrate may have a major surface, and the optical coating may be disposed on the major surface of the transparent substrate and form an air-side surface. The optical coating may comprise one or more layers of deposited material and one or more light-altering features which may reduce oscillations in the reflectance spectrum of the coated article. The coated article may exhibit a maximum hardness of about 8 GPa or greater, have an average photopic transmittance of about 50% or greater, and exhibit an angular color shift of less than about 10 from a reference illumination angle in a range of 0-10 degrees to an incident illumination angle in a range of 30-60 degrees relative to the air-side surface.
