Actually, features like the stills frame rate seem to put that theory to rest.

This is the first paragraph from the overview description of the camera on the Canon US website:
"The EOS R5 builds off of the powerful legacy of Canon’s full frame cameras offering next generation refinements in image quality, performance and reliability. It’s an ideal choice for a large range of photographic and cinematographic environments from weddings, portraits, sports, journalism, landscape, cinematography and more. "
I think that paragraph provides a good sense of how they are marketing the camera. Yeah, video is mentioned but it is not the only thing by any stretch that is mentioned and it is not mentioned first or emphasized more than anything else they mention.
The specs also follow that line of thought.
Most people will be buying both for photos too, regardless of how many video heads consider one or the other. Most reviews on Youtube tend to be video heads because Youtube is video. When number of purchases is tallied, the photo side is going to dominate.
The R5 also competes with the A7R iv sales for resolution. Because there's people moving from the 5DSR right now to the R5. It's because plenty of photographers are looking for something in the 50 MP range more so than 61 MP or 75 MP. And the Sony A7R iv is in the 50 MP range.
