As stated above, bots seem to all have increased view range, so the point is moot there. However, if you fly in a team scenario (CCW, Air Raid, or the current Round Robin Tournament), there are no bots, and the key to victory is to see the enemy before they see you.
Like Losty said, camo on GAs is practically a must have. Skimming along nap of the earth at 50 meters or less, you can scoot right under opposing formations and get to the juicy targets behind them, without being spotted. Of course, once you hit a target, you ping the minimap, revealing your location, even if they don't have eyes on you.
I have not noticed any appreciative benefit from having camo on planes that fly above 100 meters. However, I have camo on all of my planes for the simple reason that I make a lot of videos of gameplay, and having a cool camo pattern, nose art, etc, makes for a much better aesthetic.
Finally, purchasing camo for gold simply makes it permanently available to you. Like RS said, you can purchase camo for silver (3 days or 7 days), and test it out yourself.
