Sounds like your panel is on its last legs so to speak. 
Might be time to look into replacing the panel. Running a high contrast can lead to a shorter panel life which may cause the occurence of dead pixels.

Cracked screen & white dots appearing since the crack appeared


I have a Mitsubishi TV and had the same problem. There is a mirror that moves to control each pixel. When some of them fail to move you get the white dots. Google your problem and a company will come up(sorry forgot the name).,you can buy the new part from them and they have exact utube videos to help you do the repair. Took me about an hour. Part was around $150. Very rewarding feeling when you turn the tv back on with no white dots.Still dot free after two years

White dots appearing on Samsung TV screen and multipling each day


It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

Random dots or pixels failing on a DLP TV will be a bad DMD chip. This is a technician replace item only. The chip runs around 160 dollars list price. The part number will depend on which version the set uses and will be determined by the technician.
