There is NO such thing as "tube" or "transistor" sound! Only a CIRCUIT has a SOUND! The big advantage a solid-state device has over a vacuum tube is that the former is free from aging effects.
If “only” a circuit then why does tube rolling change sound? The lightbulb analogy is good - circuit stays the same but the type of bulb produces a specific result. Also, saying SS gear doesn’t age? So caps don’t go bad? Class A’s don’t burn up? Chips don’t fail?
