I’ve met a couple people who did. One guy did it like 15ish years ago and I could tell there was something there but looked more like an odd patch of skin. There was a girl I was talking to at work that had one removed relatively recently (like 3ish years ago) and I couldn’t tell there was anything ever there. Someone else must have better data but this super small sample indicates to Me that modern tattoo removal has greatly improved. It could have been differences in skin type or tattoo colors or whatever but I like to think it’s the advancements of the technology.
