At least if the guy knows what he's doing. I can imagine that plenty of self thought hobbyists and youtubers etc aren't aware of this and just 'play around' until it looks acceptable to them. But ask any big studio that knows what theiy're doing and they will confirm this.
True, most professional scripted content is going to be done as linear float internally. But the source and output formats very rarely are live linear, which is what gets to the encoder. And no distribution codec encodes in linear.

Although I hope we get one someday. ACES has demonstrated some good visually lossless compression with linear float, and I think a lot of block-based motion compensated techniques in the frequency domain could be applied to linear float.
