Is this a result of "very good" symmetry? - Need pro advice

Below is a diamond that is marked with a "VG" symmetry. A fellow diamond expert told me that the symmetry is the reason for the washed out "arrows" in the picture. I wanted a 2nd opinion before I pulled the trigger.

Diamond photography is whole another subject.
First, the diamond is tilted to left.
Second, the arrows are visible from very specific distances and lighting conditions
In short, the diamond is not photographed to highlight arrows properly.

Unfortunately, GIA report does not provide specific reasons for deduction in symmetry.
Looks like a beatiful stone regardless.

I've read a lot of bad things about "very good" symmetry on other websites. Is it really as scary as they make it sound? Will the light performance suffer?

Sarin report shows that it is potential GIA Ex in symmetry.
ASET shows it is potential AGS ideal in light performance.

Again, there is no way to know why it got a hit in symmetry.

It is a good performer regardless based on the proportions and ASET image from Sarin report.

I don't think that picture reveals any symmetrical issues. The issue that your friend talks about is not related to symmetry in my opinion.

The picture is taken with a microscope and not a photography system meant to photograph diamonds.
