Log is just a curve that save image differently. Extra data are in chroma sample (4:2:2), bitrate and bit depth (10bit). For example log in 8bit is absolutely useless. You wont get higher dynamic range, that is what size of sensor does.

And that curve allows you to process colors/contrast with way less artifacts than a file saved with a more contrast/saturated colors especially if you compound your after effects.

Btw are you a photographer or a video editor?

It might in some situations, but generally you will deal with banding anyway (8bit). Log needs higher ISO which means lower dynamic range [1]. Flat footage lacks depth so you'll need edit it, which create a new space for error.

Yes, I do audiovisual production and postproduction for living.
