Here's the original sentence: 1. The band U2 WAS just one of

Here's the original sentence:

1. The band U2 WAS just one of many new groups on the rock music scene in the early 1980's, but less than ten years later, U2 HAD fully ECLIPSED its early rivals in the pantheon of popular music.

Why not use here the Present Perfect in place of the Past Perfect?:

2. The band U2 WAS just one of many new groups on the rock music scene in the early 1980's, but less than ten years later, U2 HAS fully ECLIPSED its early rivals in the pantheon of popular music.


The only difference between these two sentences is the usage of Past Perfect (1) and Present Perfect (2).
Could someone clarify this difference, please?
My first two questions in mind are:
1. In the first sentence, does the "HAD ECLIPSED" inform that the effect of this event is not true today?
2. Does the usage of the Past Perfect in (1) follow from the general rule: Simple Past + Past Perfect, Simple Present + Present Perfect, and thus is semantically (not gramatically) indifferent?
3. If not, what is the semantical difference between these sentences?
