I've got a Dinc, DX, and T-Bolt. Got them sitting side-by-side, screen brightness at max/100% viewing Google Maps in plain map mode (very light background). The DX is by far the brightest and whitest of the three. The Dicn has a sort of greenish/brownish hue, and the T-bolt has a pinkish subdued color tone to the very light colored backgrounds.
The T-bolt is very pleasant to look at really--not as overly saturated (to my taste) as the Dinc, and not as stark white and bright as the DX. But also perhaps not as true to color? Dunno.
I don't pretend to understand the technology of these screens, and perhaps these variations are inherent to the particular screens.
I'm a week into my T-bolt purchase from local VZW brick-and-mortar store, and I'll think I'll swing by there and a Best Buy and look at display models next to phone.
