The Tournament Committee at Augusta National has always tightly controlled what is seen and heard during The Masters going back to the beginning. Do you remember when ONLY the back 9 was shown on TV? That wasn't a CBS decision that's for sure. In years where weather has not allowed the local fauna to develop and/or other reasons interfered with the appearance of the course they have painted areas of brown grass to green. Many clubs do even around here if there is an unsightly area before a big event such as the Member/Guest etc. I have had to clean my ball of a green hew many times after (finally) reaching the green. So the committee has painted a bit, they have planted trucked in Azaleas because the locals aren't ready yet. They have allowed CBS to add bird sounds to the broadcast (they don't pipe it around the course, to be clear). No biggie.
Maybe 2011 was a great year (blazing hot), the place was beyond beautiful in person.
