Meter profiling is a different service for DIY calibrators with i1D3 or similar colorimeters who want them profiled in house on their displays.
Express Plus is a calibration service for TVs with less extensive adjustments in simple systems where multiple modes are not needed. For people with budget displays and simple requirements it can get you a precisely calibrated image at a reduced cost. There are certain displays that are NOT well suited for it, though, like JVC projectors.
ISF covers everything video related for your display.
Chad stopped by yesterday to calibrate my X590R and all I can say is WOW the PQ is just beautiful. He spent about 5hrs on my projector and before he did my audio last year. You will not be disappointed in his work thanks Chad.
