It does shine somewhat in certain lighting conditions, you're right, but not as much as most other tapes. I can get 7 - 10 days with it but by then it's becoming a bit messy, not nearly as bad as blue lace tape, but not as solid as say Duotac which seems to retain its consistency for longer. You can dull the shine down by wiping the surface with a bit of the tape backing before attaching the hp.
