Have only used the 702 Bright on the Alexa Mini. Was good for viewing outdoors, but made it hard to get a feel for the image when working indoors.
You nailed it! We picked one up today and it really is great, especially since Im coming from a old DP6. Like you said though, indoors I had to turn the backlight down to 0-5% to get it where one "might" be able to expose by eye. If I were getting a monitor for controlled environments(indoors) only I'd probably go with one of their OLED units.
