friend there is basically a rule that will determine how much of proportion you are going to look like due to lack of precision,
you get the same height-x-span ratio so you're probably at the limit,
if your arms when they are down are lower than your hip even with a 7cm stretch in the femur this will not be noticeable for your proportion when you are in clothes normally you will probably only notice the difference if you compare to other people with 170cm you might have noticed the difference more nothing too disproportionate,
on the other hand if your arms are stretched down to reach hip height or less then that difference will be much more disproportionate.
for example the following photo of the UFC fighters conor mcgregor and artem lobov.

height: 1.75 (5'9)
wingspan: 1.88 (6.2)
artem lobov
height: 1.75 (5'9)
wingspan: 1.65 (5'5)
detail the conor mcgregor probably has wingspan 6'2 because of the broad shoulders what really matters is the arms naturally at the height of the mid-thigh
