When the director/producers were able to use real footage of historical events, they did an impressive job with CGI to integrate and meld younger Forrest into the footage. But I don't think there's any official record of Elvis being at Forrest's house :) so they had to create this encounter.
As Forrest is always the main character, in this case, Elvis (not even close to being "The King" at that time) is just a 'second-tier player'. I think that him being in the background/blurred is just normal. If you want to extrapolate, only after Elvis has met with Forrest (and get that pelvis move from Forrest) he'll become famous and be brought into the foreground.
