For that image? What's up with the moon and why is it so close? Is it inhabited and indeed, does its proximity effect the planet in some way beyond simple tidal forces? What's with the low cloud cover? Is the atmosphere unusually thin? Are those lakes of water, or so sort other liquid? If it's not water, is it dangerous to go swimming? Is it even liquid, it could be frozen from the looks of it. Why do things looks sort of hazy? What's up with those blue/purple bushes? If that is the local star to the left of the moon, is it flashing or pulsing for some reason and if so why? Why is the sky that color?
Wouldn't it break your suspension of disbelief if they wondered about such things all the time? With the possible exception of Enterprise (where they did have some such scenes early on), it would break mine: remember that spacial exploration has been a cultural reality for centuries by the time of the TNG/DS9/VOY era, so it's only natural that they wouldn't question why a particular planet has bigger/smaller satellites or a purple sky: they're used to visiting vastly different worlds by then.
It would also be poor writing, to be honest. Such expository details belong squarely in the "show, don't tell" category.
