Tundra wolf (canis lupus albus ) is often described as being light grey with sometimes reddish tint. A bit like this one:
(Taxidermy exhibit at the Museum of Zoology, St. Petersburg )
However almost all the verified photos and footage of it I find on the internet (by verified photos I mean either form inaturalist or whose locations are known, not the first photos that pop-up in google image) portrays wolves which look like usual Eurasian wolves rather than the ones described on in taxidermy.

Then I stumbled upon a documentary about Russian/Soviet animals where you can see several individuals fitting the description, but also some fully white wolves (which I thought were only found in North America) and some fully black wolves.
Link to the documentary in question: Documentary about tundra wolves (it’s a part of a serie). the segment about wolves starts at around 42:30. The fully white wolves are seen at around 44:25 and 44:50.
So, my questions are:
Do you think those wolves in the footage are genuinely tundra wolves from the old world or did this documentary used stock footage from America (some documentaries do it nowadays)?
Why are photos or videos of tundra wolves who fit the description almost absent?
Do you think the description of the tundra wolf in Wikipedia or in the internet is accurate?
Thank you in advance for your help
