Just curious, how did you get 8 cm off the correct height? Did you use an online conversion tool?
The only other time your height will be an issue is if you are ever arrested , and the police note your "vital stats", and hope that never happens for you.
Also, did your doctor not measure your height during the medical exam? Now, that would be on the medical report at CIC, but it is not a major issue. Hope your eye colour is mentioned correctly, for if its not, that will be a major issue ( a combination of a different height AND eye colour would make you a different person, and you could be arrested for misrepresentation!)
