Return from the third maintenance, the condition of the spark plug

12 I had my third maintenance this week, which should be the last maintenance before going out of insurance. The spark plugs were not replaced during the last 20,000-kilometer maintenance. This time, the spark plugs were replaced. Two of them were darker.
I am the first batch of B48TU of 20 standard shafts.

Used 28000 kilometers of spark plugs
Comparison between old and new
It does look like two spark plugs are darker
The oil tested before maintenance, but the 5.75 liters added last time must theoretically be at the maximum value
This time, the oil and 4s said to add 5.25 liters to see how the follow-up situation goes.
I used engine oil for a year
Add 5.25L of oil this time
The average fuel consumption during this maintenance period is 10.0L, which is not bad. I am a fierce driving style.
According to the maintenance manual, the brake fluid was replaced in the third year
