Are you sure you are comparing the exact same lighting conditions? I’ve had mine for a similar length of time and find that there are conditions where the back light makes hardly any difference and others where it does.
Because of this I wish they would make the heart rate and GPS indicators at the beginning of an exercise bigger and contrast the background more so I can more easily see whether the watch is ready for me to start my exercise. I’d also like a regular (non exercise) watch face with white background and black letters and numbers
I love the watch otherwise.
