I don't believe in copying picture settings online. Buying a disc will help you with contrast, brightness and sharpness.
If you want to calibrate your display. You need software, metre and test patterns to set the colour management and white balance settings. Calman home for Samsung is what you need. You can pick up colour metres from amazon for around 200 sterling.
I bought a metre and CalMAN software to calibrate my LG CX. My CX has an internal pattern generator so external hardware was not needed. Free mobile forge is a handy app for pattern generation as long as you have an Apple TV, Chromecast or Amazon Firestick.
If you don't feel confident doing the job yourself. Go over to AV Forums who have certified ISF calibrators through out the UK. Who would calibrate your display for you.
