If I get you right Ronster, I think you're trying to describe a *very slightly* more gradual 'gradient' of blue aura/haze/atmosphere effect around Hoth in certain closer shots of it. Like say, there would be a quite pronounced shade of blue nearest to the surface of the planet, which would then fade gradually out to even more transparent and slightly less noticeable 'shades' of faint blueness against the blackness of space.
If I'm getting you right on that, then I agree, despite some of the pic examples above giving differing results. It's quite a subtle effect, but it can make a difference. And it would apply more to shots of Hoth that are nearer to us. While that would be a nice, if very, very subtle addition, it's no biggie I reckon.
The thing is, ImperialFigher, that's not haze or atmosphere in the pic Ronster posted. It's bloom created by light convolving inside the imperfect camera lense, caused by close proximity to the planet. It's the same effect as if you hold a light close up to your face in a dark room, the light bounces around inside the lens of your eye and so you get a bleeding effect around it. It's an optical illusion.
I hate to belabor the point, but I'm just trying to get across that this is not a matter of atmospherics, it's a camera artifact. Sophisticated cameras and image-processing can eliminate this light bleed, so it's not right or wrong for the image to have it, but it's a lot less likely to be apparent at a distance, because the planet appears less bright. In the image below, the sun is the brightest source of light, so it has an aura, while the Earth, as a result, has a clean boundary.
