Exact color matching is very difficult. Check your software and monitor documentation for information on color matching and calibration.

In the Professional Mode, when Document is selected for the Auto Exposure type, EPSON sRGB is embedded even if other ICM/ColorSync setting is selected.

Printed colors can never exactly match the colors on your monitor because printers and monitors use different color systems: monitors use RGB (red, green, and blue) and printers typically use CMYK (cyan, magenta, yellow, and black).
