Hmm... maybe.... my sister reads about as fast as I do I think. I know my brother is very decent but I don't think he reads as fast as us. I think it would take a much larger sample size to start to really understand it. Wonder if that has been done before?
ok..I did a quick search and one of very first results was a scientific paper specifically on this topic.

I saw another one authored earlier by the group that did the 2023 paper in 2021 however it was behind a paywal. It's looking like you are probably correct or that it has a very large effect if not the only one Sirtel.
here is the conclusion of the first paper.
This chapter has demonstrated that several dimensions of reading such as reading
sub-skills, reading brain areas, functional neuroplasticity (of reading), the dyslexic
brain, positive affect and cognition are effected in the brain as neurobiological

dispensations caused by genetic underpinnings of individuals. Therefore, reading
must be viewed in its totality as a genetic ability that causes inter-individual dif-
ference in learning ability. Such a view is a prerequisite to understanding differing
reading environment needs for dyslexics and healthy learners with differences in
gene expression. A great deal of evidence pointing to neurobiology and genetics of
reading ability suggests the direction of personalized learning that reading class-
rooms must take. Only a holistic approach to reading and switching to personalized
learning methods will help us effectively tackle the inherent learning gaps between
individuals
