How the Ring effects the wearer is important. In the LOTR it was portrayed as a harrowing, dangerous endeavour. Sauron would sense the use of the Ring, and he could speak to, and maybe even sense the surroundings of, the wearer.
I've had a few thoughts on the subject as of late . . .
However, I think the best way for PJ and company to explain the differences is thus:
Sauron had been hiding in Dol Guldur for a long time, but he had not chosen the site simply for it's remoteness. It was also very close to Gladden Fields, the place where Isildur lost the Ring.
As Sauron is still in hiding in Dol Guldur, he is obviously still too weak to show himself. In this weakened state, he may or may not be able to sense it's use. If he can sense it's use, he may not be able to contact the wearer or sense his location. He may not want to show his power as of yet . . .
In the LOTR, when invisible, there are a great deal of 'turbulance' and the colours were often reminisent of the colour of The Eye. I expect the colour will be gone and the 'turbulance' will diminish . . . otherwise, I can't imagine PJ would make it TOO different from the Trilogy.
"I am Gandalf, and Gandalf means me!"
The Road goes ever on and on
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can,
"Thorin sat up with a start. 'Something is not right,' he muttered to himself as he stood up and looked towards the mirror . . . . . . . . . 'Durin's bones', he gasped, 'what's happened to my beard?'"
