Update -
I spoke with Rob Fairfield from Stone Pro in California and he told me that that the absolute Black granite tile is treated with Tenax uniblack 1 and will need to have this applied as the citric acid in the cleaner has removed some of the dye already in about 20 tiles.
Anyone know of a Mass or RI contractor that can handle this.

Wow. I've never run into this, but I am sure glad to know about it in advance!

There is no way to tell what product is on the floor. Uniblack 1 is a good guess, but unless you get confirmation from the person that applied it, it's only a guess. It could be a dye, or any number of or enhancers. If it is only the color that is affected, then the sheen on the stone will be uninterrupted across the damaged areas. If this is the case, then follow Rob's advice
If the sheen is gone from those areas, then it is etched as well and will need to be refinished with antiquing brushes. not many people are equipped to take this on in a house.

Rob Fairfield is awesome at stone troubleshooting, for sure! And so is Cameron...great info here.

I agree with Cam-no way to know what was used exactly to bring out the depth of color on a honed granite.
Doesn't look leathered to me just honed-we do a lot of these in our area.
However most likely it was a color enhancer which will etch or degrade when exposed to household acids like acetic, citric, etc.
Stronger acids like hydrofluoric and others can etch Granites severely.
Generally we will hone off the etched/damaged color enhancer(using 150 or 250 grit honing powder) and reapply a similar color enhancer.
Black absolute is very dense so the enhancer is topical and can be removed using abrasives.

Thanks for all the input.
The stone and tile vendor has connected the homeowner to a stone restoration company in the greater Boston area who plan on honing and then reapplying the enhancer.
I'll post a picture of the floor when its fixed.
