I’m at a trade show all weekly so I stopped in the Canon booth and spent a long time talking with one of their experts about the R5.

He then me that the R5 sensor slightly boosts voltage as you increase ISO,

Not slight but in proportion to the ISO setting.

and it did so in one stop increments.

True of many Canon bodies including the R5

Intermediate ISO changes are made post sensor read,

True of many Canon bodies including the R5

so he said that you can get a cleaner image at a higher ISO setting that falls on a full stop boundary, than on an ISO setting which is between 1/3 to 2/3 stop lower.

I strongly suspect that the effect on image quality is not noticeable.
