origin to center mass problems

hey guys noticed this thing can be weird sometimes. especially with this problem now. i got a HP version and low polly version and the low polly object is the exact same just without subdivision mod and a some edge loops to sharpen it out

heres whats weird is that the high polly version when i go to origin to center mass, it goes more towards the top. the low poly, it goes right in the middle. they are both in the exact same spots and the same size. and in edit mode, the origin will be the same as the high poly one. but in object mode like i said, its right in the middle

upload sample file so we can analyse it

happy bl
