sacrifice always blunder?

Does the computer always register sacrifices as blunders?

For example (I have others though), I just played a game where I sacrificed my rook to force mate in several moves. The upon analysis I found the computer registered it as a blunder, despite it forcing mate in several moves. In fact after the sacrifice the computer found an even faster route to checkmate than me - in 3 moves!

I’d post the game but I don’t know how.. if anyone can explain how to do that, I’d greatly appreciate it!
