It looks pretty filthy to me, but I have always been a bit obsessive about stylus condition! You need much higher magnification to be able to judge the condition; around 100x. What you are looking for are any flats. The tip should have a smooth radius and closely examine the flanks where it will contact the groove walls for any flats starting to form. If you get your lighting correct any flats will show as bright spots. You should be able to find some pictures on line showing stylus wear.
