Does your Note 5 have different color for Home button?

The home button on my new refurbished Note 5 is having a different kind of golden tint which doesn't match the actual phone color. It's not some kind of sticker on top of the Home button. Does anyone else have similar colored home button? I wanted to know the source of these refurbed phones, so if anyone else has a similar phone do you mind sharing from where you have purchased it and when? These phones also have a strange model number (SM-N920F), wrong IMEI and modified software with rooted kernel and KNOX 0.
