I have dealt with holograms quite a few times and have previously talked to a co-worker who has been detailing for 30+ years.
Without exception, the most common comment I've heard for over 20 years now after teaching a detailing class is from someone my age or older and it goes like this,
"If found out today I've been doing it wrong for the last 30 years"
Seriously.
Most detailers, especially older guys are self-taught. Nothing wrong with this but it is kind of limiting.
Something I type on the forum all the time and if fact have an article on, goes like this,
Detailers that hang out on discussion forums know more than detailers that don't...
Does your buddy hang out on detailing discussion forums? If not... share this forum with him.
In FACT the only way to keep up with the rate and speed that new products, (new technology), being introduced to the world is to be on a forum like this one because new products and technology breaks on forum long before it creeps out to some guy in a garage or shop via a Wagon Jobber.
And since I called on PBE and Hard Parts stores for 3 years once in my life trying to educate the countermen and counterwomen on both old and new products, I'm hear to tell you that 99.9% of these people are not going to be able to help you and all they are there to do is ring you up with whatever you bring to the counter.
To your question... as others have said, "yes" holograms can be removed. The limiting factor is,
How deep the holograms or circular scratches are in the paint.
How thin or thick is the paint
The factory clear coat on most new cars is right at 2 mils, that's thinner than a 3M Post-it Note. Hold one between your fingers and this will drive the point home REAL FAST just how thin this layer of paint is. And for this reason, it's an absolute CRIME for some hack detailer to fill someone's new or used car with holograms.
Think about this...
Buffing a car out using a rotary buffer and instilling holograms into the paint removes paint and leaves scratches or voids in the paint.
That's a bad thing.
For someone that actually knows what they are doing to come along and remove the swirls by correctly buffing the paint to level it or flatten it out will also remove paint.
Now paint has been removed twice and it's all been totally unnecessary. Completely unnecessary. But that's our "system" archaic as it might be.
Here's a couple of articles on this topic, the second one there's a bunch of guys making jokes about the article but regardless, it's true. And...

What it means to remove swirls, scratches and water spots out of automotive clear coats
And here's the article everyone makes a joke in and the comments are funny but I still stand by what I wrote.
Swirls and Scratches Don't Exist
