I have stacks of unfinished red oak and white oak in my piled up in my living room.
The floor in that picture is definitely oak. The question is if it's red or white.
The best way to tell the difference is to look at the cut edge, but you can't do that when it's already on the floor.
The next best way to tell the difference is the "rays" which are the little streaks that go through the wood.
Red oak has shorter rays and white oak has longer rays.
I believe that the flooring in the OP pictures are
red oak because the wood appears to have short rays.
The reason you don't think your floors are red is because they aren't stained, they are just clear top coated.
But the picture you provided isn't close enough to be certain your floor has short rays. Here's a picture of red and white oak side by side:

Look at your wood. Decide if the rays (little thin lines) are short or long.
If they are short like the right side, you have red oak. If the rays are longer like the left side, you have white oak.
