Beretta used to have two different processes to enhance the woodgrain.
One was called X-tra-grain which is what the OP is describing with the laser enhancements.
The other was called X-tra-wood which some kind of hardwood with the film overlay which makes it look like exhibition grade walnut. I don't know what they are doing nowadays, but that is what I found 10-15 years ago.
The original post mentioned ExtraWood, so that's what I was basing the response on. I had never heard of the ExtraGrain.
They all kind of reminded me of the plastic stocked single shot shotguns of the 50's and 60's.
