An electronic device may have a display panel. Light from the display panel may be focused by a lens assembly towards a viewer. Optical crosstalk, off-axis color shift, and/or the presence of the lens assembly may cause color non-uniformity in images viewed through the lens assembly. To obtain color calibration information, first information may be used to simulate the color of the display panel when viewed through a lens assembly from a first number of points. The first information may include an average display panel color emission profile and a map of correlation between pixel locations and incident angles and corresponding pupil locations and gaze directions. The color of the display panel through the lens assembly may be measured at the first number of points to extract a lens non-uniformity contribution. The lens non-uniformity contribution may then be used to simulate color at a second, larger number of points.
