What you’re seeing is chromatic aberration - probably from the lens, but possibly also from the sensor or something else. It’s not unusual. If you have chromatic aberration correction enabled in PhotoLab 9, zooming in >50% should show the correction (and apparently does in your case). CA is not corrected in the image viewer at all zoom levels, but will be corrected on export.
See here for a discussion about this and an improvement in previewing noise reduction:
