I have noticed my wife's 2016 Accord I4 oil dip stick can have two different readings when you check oil as hot and cold. The difference could be as much as 3mm apart on the dip stick.
There are some augments on the Honda forum when to check, so I like to post what I found here.
Going through the owner's manual I found it said:
Oil Check
We recommend that you check the engine oil level every time you refuel.
Park the vehicle on level ground.
Wait approximately three minutes after turning the engine off before you check the
oil.
1. Remove the dipstick (orange).
2. Wipe the dipstick with a clean cloth or
paper towel.
3. Insert the dipstick back all the way into its
hole.
So it supposed to check when its hot.
That's how I filled it last time.
