By default, the watch settings are optimized for battery life and performance (Tips for Maximizing the Battery Life).

Image persistence, or pixel "burn-in," is normal behavior for AMOLED devices. To extend the display life, you should avoid displaying static images at high brightness levels for long time periods. To minimize burn-in, the fēnix^® display turns off after the selected timeout (Display and Brightness Settings). You can turn your wrist toward your body, tap the touchscreen, or press a button to wake the watch.
