Rollers make you smoother. I said that. They do not make you faster.
The Worlds ITT and TdF ITT riders are seen warming up on trainers rather than rollers because it better fits their "herky-jerky, ill-balanced, halting and/or plodding pedaling style combined with tense erratic steering inputs", as they go faster.
Rollers are recreational things that all good riders should know how to do, but less than the ideal training tool.
