I'm no expert here but if me, since they clearly are working, leave it.
If you look at the timings, they are both at 15.15.15.35. They are both PC4-19200 (2400MHz = 2 x 1200MHz). There is a difference in latency values between CL16 and CL17, but this difference is less than 1ns (1 nanosecond = 1/1,000,000,000 or 1 billionth of 1 second).
Note DDR = double duty rate. Hence 1200 x 2.
Also, about 99% certain G Skill uses Samsung chips.
