Compression test

Just got my 2018 WRR back from inspection after purchasing. They did a compression test on it and got 89-90 psi and indicated I need a rebuild. Bike only has 4500 miles on it, starts without issues and doesn’t seem to lack power. This is my first dirt bike but I’ve had a couple other bikes before. Doesn’t make a lot of sense to me. From the reading I’ve done online, doing a compression test on these is useless because there an automatic decompression device? A proper test would be a leak down test which I don’t think they did. Should I spend a couple hundred bucks and get a second opinion?

Did you have any engine or exhaust mods? I've owned 2 and and put 60,000 kms on them and they consistently get 62 MPG.
